From working in retail for years at a convenience store, I can say that my job has really tested my mental strength. Sometimes it's really hard to distinguish whether dealing with customers makes me a more patient individual, or just a more annoyed and stressed out version of myself.

Whenever I clock out, I question my sanity and wonder how I survived to tell the tales. All in all, these little things that some customers do and say are all too real, a real pain. But somehow, us retail workers have made it. I just wish I knew beforehand that the job position required blood, sweat, and tears.

1. No matter how kind you are to customers, some still can't break their grumpiness.

Seriously, it's one of the most annoying things on the planet. First of all, it's not my fault that you had to leave the comfort of your own home. Second of all, don't leave home if you're going to be like that.

2. You ask, "How are you?", and you either get an unamused, "Fine", under their breath or nothing. Nothing at all.

Sorry to offend you, but I'm also going to throw in a "Have a nice day!" as well.

3. Scenario: A woman comes to the register with a whole bunch of stuff, so you start to ring her up. Everything is fine until she calls out to her kids across the store to hurry up because she's checking out. There is a loud exchange of dialogue and then, suddenly, five family members run up to the register in different directions and throws their items onto the counter.

Couldn't you just figure this out BEFORE you decided to come to my register and rupture my eardrums?

4. Hearing the friendly "I'll pay" fight makes you numb.

Until the 35th time, you start to see the light. They say, "Oh, just let me treat you", and the other one succumbs. That's when they remember that you've been standing there the whole time.

5. You witness people just standing around in some sort of daze all the time.

Sometimes you have to pick your battles and not ask how they're making out.

6. Random guys stick around longer than the usual customer just to compliment you and ask you about your personal life.

Dude, go to a bar if you're looking to find someone to flirt with, not your local convenience store.

7. They're talking on the phone while you're taking care of them, and then they ask you to repeat what you said to them.

That's not how it works, ma'am. If you missed it, you missed it.

8. They act like they're in a rush, so they do one of the following things: throw money at you, don't speak to you at all, be on the phone, or run around the store frantically and in circles.

Or maybe all of the above.

9. They assume you have robotic abilities, meaning that you know all, run all, and can do all.

Chill, Karen. I have no idea why your card was declined and, yes, I will get you your drink. Yes, I will put extra whipped cream. Of course, I will do that for you. Let me just grow my third arm real quick so that I can handle all of your requests at once.

10. You find yourself with the urge to scream and/or cry. Your mind is constantly wondering what in God's name is wrong with these people! You just might explode with all your emotions at once.

For a moment, I thought I would lose it if it weren't for that good cry in the back room.
