I just used the last $4 on one of my fat credit cards to buy some beer. Since I'm riding the bus, I can't open one of the cans now and drink it down. In fact, I've had to go a number of days without anything, until I finally sat down and started checking card balances. And of course I was trying to do too many things before I had to go and catch the bus. And of course stop by the store for that beer.
