A day on which you pay for a meal using only dimes that you've saved from the change you get from paying for other meals. A true dimeday can only be achieved when a meal costs $x.90, and you get back a single dime in change per transaction. If the change is a large amount, asking for dimes instead of quarters is cheating and voids any dimeday using change from that transaction.

Mike: Yeah, I'll probably go for that too.

Eric: Dimeday?

Mike: You know it.
