Customer: Could you take my front brake off? It looks babyish.
Mechanic: I'll tell you what looks babyish: your face after it scrapes on the ground because you didn't have adequate brakes. You follow what I mean?
Mechanic: I know you get on your bike to go and not to stop. But one day you'll need your brakes. I'll tell you what. Next time your friends tell you that being smart isn't cool, just tell them to shut up.
Customer: I don't think I need the front brake.
Mechanic: are you in school?
Mechanic: yeah, stay there.
I swear to you this conversation took place today.
