After working at Subway for three years now, I've come across a handful of colorful characters. All of them are unique in their own way, but over time, I've seen a trend that some people share the same habits. These people are some of the customers that make sandwich artistry a worthwhile experience. I find myself liking these people, and although their antics are peculiar, there's something about these customers that I find appealing. Here are six of the most common Subway customers.

1. Mayo monsters

I'm a little biased when it comes to these customers, because I personally cannot stand the taste of mayonnaise, but these are the customers that will put extra mayo on any sandwich. You name it, they put mayo on it, whether it be a turkey sandwich, a tuna sandwich (which is already mixed with mayo), or the dreaded combo that is a meatball sub with mayo. I cannot tell you the amout of times I've crafted a beautiful sandwich, with the bread perfectly toasted and cheese melted, only to have the customer ask for extra mayo. As every drop of mayo trickles out the bottle, I feel me heart break.

2. Kitchen sinkers

Most people have heard the term "Everything but the kitchen sink," and this refers to people pilling on any ingredient in sight. Well, Subway has its share of "kitchen sinkers," and they're the people who put on any veggie we have to offer just because veggies are free at Subway. These customers know no boundaries. Some crave extra olives on a steak and cheese, some demand pickles on their meatball, and some see no problem with jalapenos on their tuna (the problems may come after it is eaten, however).

3. Daddy daycares

The daddy daycares are a rare bunch, but they make their mark. These are the parents that bring their young children in and let the kids order the sandwich. At first, one would expect a child's sandwich to be simple, as they're less than six inches, but the parents insist on explaining every ingredient to their child and asking if they want it on their sandwich. When I was little, my parents would order what they wanted me to get and I was only responsible for eating it. Today, parents let their young child pick their toppings, even though half the time, the kids don't know what they're putting on the sandwich. The most challenging part comes when the child picks what bag they want their sandwich in. This is when I do my best Vanna White impression, modeling the bags' features.

4. Bathroom breakers

Numerous times, I've had customers tell me what type of bread they want and as soon as I turn back around from the bread cabinet, they're nowhere in sight. The words "What type of sandwich would you like?" fall on deaf ears and I hear the shutting of the bathroom door. I've been struck by a bathroom breaker. I understand ordering a sandwich is an exciting event that may push your body to the limit, but in my heart of hearts, I believe that people possess the willpower to wait until the end of the experience to use the bathroom. Also, they could go beforehand, if they truly want to order their sandwich stress free.

5. Machine gunners

The machine gunners are the opposite of the bathroom breakers in the sense that they feel the need to announce their whole order at once. So, my simple question, "How are you today?" is answered with "Six-inch tuna on wheat with American cheese, toasted with lettuce, pickles, banana peppers, onions, olives, and extra mayo." I understand some frequent Subway customers know the process well, so they don't need the worker to ask them what they want on their sandwich, but it's easier for everyone if you contain the excitement and walk through, step-by-step, with the worker.

6. Hoarders

We've all seen episodes or clips from the reality show "Hoarders," and these people live lives that seem frightening and overwhelming. Subway has hoarders of their own, and the worst part is you can't see them coming. One minute you're wrapping up a sandwich, and the next minute, you're at the register as the customer pulls out five Subway cards. They ask the dreaded question, "I have a free sandwich on one of these, could you figure out which one it is for me?" The task isn't all that time consuming, but it also turns out that it's either the last card you swipe that has the sandwich on it, or the customer doesn't have a free sandwich after all, and you have to be the bearer of bad news. They may accuse you of stealing points if they don't have the free sandwich, and I never understood the accusation. Us workers are no Subway master thieves that desire your free sandwiches (we get them free at the end of the shift, anyway).

These people may seem odd at first sight, but like I said, they're generally a great bunch of people at heart who laugh at their own habits, and they're cooperative. I would rather have a line of 20 of the stated customers than one customer who is rude and disrespectful.
