Customer Service

I've worked at Mcdonald's and now I've been working at a salon doing hair and let me tell you, rude customers are everywhere. 
Do you know how many Mcdonald's employees are actually scared of the McRib? I remember when I was working there and the McRib came back, the first thing all of the employees started saying was "Oh God just wait until it leaves again." Because they knew the ass chewing they were about to get when it happened. I'm sorry you want your McRib but it's not my fault that it's now gone.
Another day I was working, there were two other people working. Me, doing everything in the front, A coworker making all the food, and a manager, trying to do her duties in the back. We were pretty well slammed too. Well, one guy thought his food was taking too long since the guy building the sandwichs was also trying to cook everything at the same time while I'm bagging other orders and taking orders. So I get him his food maybe two minutes later and he's not happy. I apologize and try and explain the situation and he throws the burger at the wall and leaves. Not really sure what he accomplished there. Cool, now you're out all that time, out your money because we're not refunding that, and you're still hungry. Good job bro.

Another thing, if you ask for something in the pull forward section of the drive-thru, please just don't come back to that place. You've had three other chances to ask. At the pay window, the drive-thru window when you get there, and when they ask you to pull forward. If you ask as I'm bringing you your food, you're not getting it. Especially if we're busy or it's cold as shit. I'm not allowed to wear an actual jacket back there mind you, because it "has to be black" and I don't have the $50 to buy me a brand new heavy coat, in black. And if it's just busy, I'm gonna get my ass chewed out for going back outside because they need me in there. I'm just not doing it. It's not worth it to me. You don't even tip me, and even for those few nice people that do tip us, there's only a slight chance we'll be able to keep it.
Fun fact: Mcdonald's employees are supposed to give their tips up into the Ronald McDonald house charity.
You're telling me, I'm working my ass off for minimum wage, begging for less than 40 hours a week, the maximum I'm legally allowed to be scheduled without my permission, and now I can't keep a tip if someone decides to give me one? That's a rule you can shove up your rich ass for all I care.

Then there are just the stupid customers that just don't listen I guess.
Customer: "I'd like a child's happy meal."
Me: "Hamburger, cheeseburger, or nuggets?"
C: "Yes."
Me: ??????

Or, one of my favorites.
C: "I'd like a (Insert sandwich here)(I forgot exactly what he ordered)
Manager: "Would you like Beef, grilled chicken, or crispy chicken?"
C: "I'd like meat."
M: "Sir, they're all meat."
C: "I want meat!"
M: ??? "Uhhh..." *Clicks random button* "Beef it is."

What are we going to do about it though? There's always going to be stupid, unruly people wherever you go, I guess.
