Mechanics prefer to wear shorts.
One of the most popular sayings from customers is: "I know nothing about bikes but..."
Never lend a chain tool to anyone, they will break it.
I'm moving into five months at the shop and will soon be starting a slightly different role as a full time mechanic. I will only work one weekend in three so should be able to organise my racing easier, although it will be an intensive learning curve at the same time.
Bring it on.
