Lil Scrappy

Scrappy tells TMZ, he was scheduled to perform at Club Vizion Sunday in Louisville, KY, but when he showed up to do the show -- the promoter didn't have the money to pay him ... so Scrappy refused to take the stage.

Crowds of people had already shown up for the performance -- so Scrappy says the club owner paid the rapper a small sum to do a meet-and-greet instead of a show ... and Scrappy agreed.

When all was said and done, Scrappy says he went back to the hotel the promoter had arranged for him -- but the hotel informed him his reservation had been canceled and he was required to vacate.

A source at the hotel says cops were called to assist in Scrappy's removal -- but the rapper says he left voluntarily.

Scrappy tells TMZ, he has no plans to sue the promoter -- but vows never to work with him again

The promoter had no comment.
