Justin Bieber I Got a Big Tip for You ... Or Do I

Justin Bieber got comped big time for a bar tab at an Atlanta club and left behind a tip that has our newsroom deeply divided.

Justin and his entourage were in the ATL last week for Jingle Ball. After the performance the party moved to Tongue & Groove nightclub, where Justin ordered up a storm in bottle service.

- 2 bottles of Don Julio 1942 ... $500 each
- 1 bottle of Grey Goose ... $300
- 1 bottle of Jack Daniels ... $275
- Some beers ... $25

The table total was around $1,600, which the club comped. The Biebs left his 2 waitresses $200 each. We're told Justin was amazing with interacting with the staff and club guests, and even entertained the packed crowd by taking photos with them.
