Guy 2: Yeah, but there wasn't alot of people in the seats, and the ones who clapped gave a courtesy clap.
This sort of clapping is seen at churches, schools, business meetings, etc.
Bro 2: Dude She is such a bitch! Why would you go there?
Bro 1: Don't worry man, I gave her the Courtesy Clap, she won't be back.
