Fetty Wap was like, "Hey, what's up? Hello," at an Olive Garden Thursday night ... and then he bolted without paying the bill.
Fetty was dining with a group of friends at the famous franchise in Wayne, NJ when he stormed out of the restaurant.
We're told he threw down $100 for the apps and drinks, but by the time he left, the bill swelled to $160 ... possibly leaving the server on the hook for $60.
Fetty says he was there for 2 hours and the service was so slow his food never came, so he said "arrivederci."
But Olive Garden employees say he was there for only 30 minutes and it was a simple case of dining and dashing.
Happy ending ... the server didn't have to pay.
We couldn't reach Fetty for comment.
