Chicks in Thongs Fighting

Usually when I go to a Chinese restaurant I expect a smile, some egg drop soup, pot stickers, and some mongolian beef finished off with a dry fortune cookie. Apparently I've been going to the wrong one since Chin Chin or PF Changs don't have chicks in thongs destroying the shit out of the joint while fighting with no pants on. Seriously what the fuck happened to their bottoms? Trust me I'm not complaining but I'm utterly confused. Have bottoms become optional in Chinese establishments?
