Usually if someone called you a deadbeat you would take it as an insult. But there’s one exception to this rule.
Deadbeat is the term used by credit card companies to describe people who wisely pay their bill in full every month. These deadbeats have the nerve to take advantage of the convenient nature of credit cards while avoiding all the finance charges associated with them. Credit card companies hate these customers because they make almost no money off of them.
But don’t take it personally. In this case being a deadbeat is actually something to be proud of.
