Wasn't expecting this

So I do this trip as I was really close to the pick up location. It's a girl maybe late 20's. Pretty cool talkative. As I'm dropping her off she asks if I accept cash (of course that's preferable lol). I don't expect anyone to tip, but this really surprised me. So I go down the road a little bit.. She handed me a $50! 50 for one of those rides where you ask yourself.. Should I take it or wait for a better one. Well this is as good as I can get! Lol
