Is That Your Number One Ik?

A lot of my friends who like go on dates also say some guys are very rude to servers or they just kind of look down on them. And I think that is a huge ik. If I was on a date with a guy and he was rude to the server, I would not know what to do because it's like I also don't want to be associated with him in that moment. So for me, that's like the biggest ik...I've been lucky enough where I haven't really seen it happen in front of me yet.
