As someone who pays with credit card I get pretty upset with people who pay with cash. People fumbling around for exact change. The person working the register has to deal with bill or coin shortages: "oops we're out of quarters hey can someone bring some to my register?" Not to mention the overhead incurred by having to deal with all the cash at the end of the day and dealing with shortages.
