The machine ate my dollar bill, the next machine would not accept dollar bills and there were no change machines, and on the way back, the machine would only accept dollar coins and quarters, and the MUNI change machine would only change dollars into dollar coins, and if I wanted to change a dollar into quarters, I had to waste time walking across to the BART machine to change my money. It took me about half an hour to do something that would normally take 10 seconds.
