Can you people pls treat me nicely?

I swear i didnt do anything wrong. but why are customer so grumpy and demanding? Its not fun working when you people come and scold us but we just cant do anything but to put on a smiley face for you! Is it our fault that 2 people before you just walked in unannounced with a huge order and they took away all the chicken that we had left, even the spare ones? And can you people don complain that its too expensive. Look at our faces, we are not the one was sets the prices. If its too expensive and you cant effort, take time to cook for yourself cos it will definitely save u lots of money. OR else can you pls listen to our suggestions?Lots of time its so much cheaper that what you just ordered. Just because of your stubborness you need to pay extra. And for goodness sake,is it our fault that you come at 20 minutes before closing, and u demand everything on the menu? Do you guys know where does all the food goes if they are not sold? IN THE BIN!!! So are we suppose to cook a whole bag of chicken for u when u order 2 or 3 pieces and throw the rest away? Isnt that just to wasteful? I know its call fast food but it doesnt really make sense when you don't wait to wait but you want it fresh? How can we do that? Good cooking takes time. So guys, can you do me a favour? Pls treat us nicely, we are always trying our best to make you happy but sometimes its just not possible because we are working under rules. So pls be a little bit more considerate next time when you're in a fast food restaurant.:) Although not all of you are like that, some are really understanding and super duper friendly. I don mind you laughing at me when i try to repeat your orders and sometimes my tongue just get twisted and my words get all mixed out. Making you happy makes me happy too plus it makes working really fun!:)
