If you've worked in the food industry or retail or both, you know that some things will really peeve you after you've heard them once or twice. There's just something about the things people do and say to their wait staff or to retail workers that make me question if that's their first time out of the house.

I've heard it all, having worked both, and I know that things can get cringy and downright annoying. But the customer service representative in me flips a switch and handles it as best as possible.

These are 10 out of the thousands of things you probably shouldn't tell someone at a restaurant or a store. No matter the status of the place or the look of the person helping you, there's just no need to be a dick about it.

1. "Oh, that's really expensive."

Fun fact: We don't make the prices. We probably can't afford it either. So do you want it or not? We don't have time to talk about the price or cut you a deal because we feel bad.

2. "It's not ringing up so it must be free!"

That's usually followed by some half-assed laughter. If I had a dime for every time someone said that I would never have to work in the food industry ever again.

3. "Are you guys open?"

Can you read? What time does it say we open on the sign on the door? 11 AM? Okay, so if we aren't set up yet and the little hands on your watch say 10:30, we're not open yet. Please don't try to come in.

4. "Are you closed?"

No one is inside. The food has been put away. The registers have been accounted for. The music is off. Our will to live has gone away. So yeah, we're probably closed. And no, we won't let you buy that one last thing that you really wanted to get.

5. "I'll have ice water, light ice, with a lemon wedge."

Alright, so you're a little too specific for me and this is actually one of those "serve your own drinks" kind of place so I'll let you go off.

6. "What should I tip?"

Listen, I don't know if you're asking me or your wife who clearly wears the pants in the relationship, but if your meal is over $50 you can at least tip $7. But go ahead and don't leave a tip anyway. We're only working our hardest to make sure your meal is the best meal you've ever had.

7. "Can you split the check?"

That wouldn't be an issue if you weren't trying to split it six equal ways. Personally, I don't have time to deal with the line out the door and your desire to split the check although everyone in your party said they wanted to pay separately.

8. "Tell her what you want."

Your kid is not cute enough for any of us to try and understand what they want to order. Just tell me they want the chicken nuggets with mac n' cheese and let me go. Your kid won't even look me in the eye anyway.

9. "I'll take..." "Give me..."

Ask for your meal nicely. Even if you don't realize that you're being rude, we'd much rather hear you say "I would like..." or "Can I have..." than anything else.

10. "Let me talk to your manager."

Before you get all middle-aged woman with a bad haircut and a minivan crazy on us, let's see if we can help you first. 9 times out of ten, our manager is going to tell you the same thing we just told you. And you can call us out on it.

The following is geared towards those in a barbecue restaurant so please bear with me.

11. "Do you have barbecue sauce?"

At a barbecue place? At a smokehouse? At a place that serves actual barbecue and sells their own barbecue sauces? Absolutely not.

12. "Is brisket a cow?"

How does one answer this politely without making the other person seem like a moron? I always make a coworker answer.

13. "I want my (Tri-Tip/Prime Rib) well-done."

So you want the king of cuts grilled until it's chewy and flavorless? You want us to take a nice, juicy, moist cut of meat and have it turned into a shoe? Sure, you betcha.

14. "It's really smokey in here."

It's a smokehouse. It's always smokey in here. We have smokers smoking the meat. All day. Everyday.
