This has been a pet peeve of mine for a while on the cash thing, gas stations that won't accept anything larger than a twenty. Give me a break, until recently $20 wouldn't get you very far, by the way I paid $1.77 a gallon for gas last night . It's is truly amazing the funny looks you get for paying cash and as far as people making change well that's a whole different story, most can't anymore.
