I usually have $100-$200 for tips, kids raising money for their sports teams, veterans, beggars, whatever and just in case the card systems are dead.

I used to carry more but can’t afford to be so generous now. Really I shouldn’t be as generous as I am, but when I see a jar a quarter full of one dollar bills and change in the jar, I dig out a twenty.

I mean come on! A dollar? Your pocket change?
