You should see the bank tellers’ faces when I go in about once a month and ask for $100 in singlesIf you buy something, you’ll get change. If you use some service that is normally something you’d tip for, like a van ride or going to an FBO, bring some $5’s. It’s not hard, I’ll go to the bank every now and then and get $50 in $5’s. Depending how much I am flying, that lasts me at least a month. Once I start doing the airline thing, I’ll be tipping a lot more van drivers, so maybe I will have to go more often.
