The art of sneaking out of a restaurant without paying, even though you have plenty of cash to cover. Usually done after bar close with a feeling of invincibility, followed with feelings of guilt the next morning.
May include anxiety over the possibility of being arrested over a Denny's Grand Slam Breakfast.
Real faint of heart will call back the restaurant with some lame excuse and proceed to drive back to the establishment with a 10 dollar bill clutched in their fist.
Denny's: Good Morning, Denny's!
Joey: Uh, hi. I was at your establishment last night and I got a call from a friend who was sick. He needed a ride to the hospital and wouldn't you know it, I forgot to pay!
Denny's: You don't say!
Joey: Yup, I will be there in 20 minutes with the $6.80. Good Bye.
Denny's: (After hanging up & speaking to manager) Last night's dine and dash will be in to pay in 20 minutes!
