I currently have one of the worst possible jobs; I work as a cashier at a grocery store. It’s not really the worst job, it’s just that when people shop at grocery stores they become some of the dumbest people on the face of the earth. When people walk into the place I work, their IQ drops by 30 points.

Because you should care about the opinions of grocery store employees, you should follow these steps so the cashiers don’t make fun of you on their lunch break:

1. Do not ask me if I work here.

Even though my nametag says “Welcome” and I am clearly wearing a uniform, I do not work here. I just wear this uniform for fun. In fact, I just check people out at registers for free, because I love it so much. But don’t tell anybody, I don’t want to get caught.

2. Do not ask me if my register is open.

If my light is on and I’m standing at my register and I’m checking someone out, I am open. It’s not that difficult to determine if I am open to check out your items.

3. Do not ask me if something is on sale.

Our sale prices change every week as well as the items on sale. There are hundreds of things on sale at once. You really expect me to know that? Just let me scan your rewards card and then the register will say whether or not the item is on sale.

4. We don’t have that.

No, we do not have more than one brand of buttermilk. And, no, we don’t have cheesecloth.

5. Don’t ask me where things are located in the store.

I understand questions about things that are legitimately hard to find because, granted, some things are impossible to find in any grocery store. But, do not ask me where the fruits and vegetables are. Do not ask me where the cereal is. And, for the love of God, do not ask me where the frozen waffles are.

6. I really don’t care if you shop at another grocery store.

People yell and scream all the time and vow to never come back. They threaten me with promises that they will be shopping at other grocery stores instead. Honestly, I don’t care. Whether or not you shop at my store does not determine how much money I make. I work for a salary, not commission.

7. Don’t tell me how to do my job.

If you work at a grocery store now or have worked there previously, I really don’t want your input. If you’re currently not in a grocery store uniform, you have no right to tell me how to do my job. I may make a mistake, but I know how to correct it. I don’t need you to tell me how you fix it at your gocery store because, guess what, I work here, too.

8. If you don’t want it, don’t make it my problem.

If you pick up an item in one part of the store and decide in another part of the store that you do not want it, you have two options. Either walk your lazy butt back to the other part of the store and return the item or, at least, give it to an employee to put back.

There is nothing more frustrating then finding a jar of peanut butter sitting on a shelf with the eggs. Even worse is finding a bottle of wine behind a box of cereal. Not only did the customer not put the wine back, but they made it hard to find.

Possibly the worst thing though is taking a refrigerated item and leaving it elsewhere where it can potentially go bad before an employee finds it.

Remember, be nice to your cashiers. Their opinion matters.
