1. So we're having a sale right? - buy three get one free. Do not come up to me with 3 items that cost $5 and expect to get a $15 item for free. That's not how it works. In no world does that make sense. No business owner on the planet is going to let you do that because then they would lose money. I cannot tell you how many times I've had this problem with customers, I mean is it not self explanatory?!

2. (This one is mainly applicable to smaller businesses) We have two cash registers but you go to the one I'm not standing at? Instead of the one I am CLEARLY standing at and have been standing at for the past 45 minutes. Sure I'll come over there and log on to that register since you can't seem walk an extra two feet.

3. Never. Talk. To. A. Cashier. Like. They're. Stupid. Just don't do it. Why is it that everybody always assumes cashiers are stupid? I've had several customers make me count back their change to them because they just assumed it would be wrong. Like excuse me sir, I'm not a high school drop out, I just have a job as a cashier. I know how to do simple math. Even if I didn't you do know that the register tells me how much change I'm supposed to give you right?

4. Look man if a cashier says hello or welcome, just say it back. My favorite customers are the ones I say hello to, look at me, and just keep walking. I really am overjoyed by their kindness.

5. If you walk into the store with a pocket full of change and nothing else, just get out. Don't even try.

6. So a customer comes up and one of their items isn't ringing up right and they jokingly say "Does that mean it's free?" Oh you're so funny! HahahahHAHAHAHAHAHA. So funny.

7. Here's one for anyone who works at a gas station. If your tank can only hold $16.73 worth of gas, don't pre pay for $20. Just. Pump. First.

8. Do I look like a stripper? Don't throw your money at me, hand it to me like a human being. Do not throw your debit/credit card or cash at me. Don't toss it onto the counter. You can put it into my hand that I am holding out like a nice person.

9. This may be one of the most annoying ones. When you click Total and they say "Oh and this too." Or if they have someone with them that brings up another item after you're almost done ringing them up. Man those are my FAVORITE kind of people.

10. When you ask if they want their card run as credit or debit. "Credit..wait no debit..wait credit...ah whichever." CREDIT OR DEBIT?????

11. Speaking of credit/debit cards, if your card is old and barely works when swiped, GET A NEW ONE.

12. When the register goes down and the customers get mad at you. Don't get all huffy with me when the technology doesn't work. Oh wait I forgot, I can press that magic button that makes everything work again. I'm sorry! :)

13. This is single-handedly the most annoying thing you can ever do to a cashier.
