In Japan, when people have a meal with friends, it's common to pay warikan, which means "split the bill equally." When you're with seniors, they will sometimes pay for everything or pay a bigger share than you. When that happens, you should show your gratitude by saying Go-chisô sama deshita, meaning "Thank you for your treat." And if you are treating others, you say Ogoru or Go-chisô suru.
Now, what about when you have a meal with your boyfriend or girlfriend? Well, it used to be assumed that the man would always pay. However, as women have become more active throughout society, warikan, meaning "splitting the bill," seems to be on the increase.
