Don't take things too literal. Oh you.
4. Never Let Someone Pick Up The Bill
Some people may have noticed the fighting after a meal in a Chinese Restaurant. It isn't because the food was bad, or that Chinese people are simply angry people that run around looking to pick fights. The reason for this is, it's extremely impolite to allow someone to pay the bill without fighting wholeheartly first.
Regardless of being invited, or inviting someone else to a meal, be sure to fight to pay for the meal. If you don't have the money at the moment, consider "faux-fighting" the bill.
"I'M PAYING FOR THE MEAL DANG IT."
