No bacon on my cheesburger, please!
Who in their right mind puts bacon on their cheesburger. Today for lunch I go to Carl's and every cheeseburger comes with bacon on it. Even the cheap cheeseburger has bacon on it. I hate that, don't you? So anyway, I order a cheeseburger and told them I wanted it without the bacon, "please". Everything was ok until I took a bite out of it and had chunks of bacon in my mouth. That was not a good day at the burger joint today. I had to pick out all the bacon before I could finish my burger. 
Species, that is nothing. Go into many fast food restaurants and more than likely they get your order wrong.
A lot of the people who work in the fast food industry are immigrants so when you order a "small fries" the person behind the counter thinks you ordered a "small Sprite". You ask for more hot sauce or ketchup and they only give you two of each.
You better say your order in Spanish where you will be understood.
You paid someone five (5) bucks to serve you a meal, and you're griping because it's not 5 Star service? Wake up. If it's wrong, take it back, repeat your order and let them pay more attention. If you don't like what they serve, don't go back, pack your own lunch, and pay yourself the 5 bucks.
Will you complain that you're underpaid, now?
I feel your pain! Annoying isn't it? Best thing to do is check your order before you sit down to eat or before you leave the restaurant if you get it to go. If your order is wrong, take it back to the counter and tell the cashier about it. Good luck! By the way I happen to like bacon on my cheeseburgers once in a while. I just don't like the huge amounts of mayonaise! Gross!
