People who still use checks for anything other than rent, mortgage, large down payments, or gifts. Such as in a grocery store line... Also, businesses that don't accept credit cards but have a fee charging ATM. Hell, if you don't accept credit cards period. Cost of doing business.
While we're on the subject, !@#$s who take up 3 ATM lines waiting for the first to open while others are behind them. Then they tend to cash every $5.00 check granny ever gave them for 10 minutes at a drive up. Money on my mind today...
