I’m looking for a movie or TV episode from 90’s series. I remember a woman-gambler. She was addicted and she played in a casino. Then, somebody wants to harm her (probably), but a croupier was sitting in his car and pulled out a fake gun (it looked like a gun, but was probably a pool cue) and threatened this thug. She was saved.
The croupier was fat man in style John Candy or John Goodman.
