You would think that people would realize that there are some conversations you should have at home, and not say, in line at a restaurant.
This guy and his wife were arguing over the fact that his wife finally slept with another woman, and liked it. I couldn't figure out why he was pissed about getting what he wanted until I heard, "“Yes it has been a huge fantasy of mine, but I didn’t expect you to sleep with my sister at a family reunion after I passed out. Now my entire family knows."
Dude, seriously, not at my favorite Chinese place. Props to your sister though.
