I'm narrowing it down from many ideas to a few, more better story ideas. here's a few short plot ideas that I will probably expand on.
Under-cover business
The manager of the gym is an ex-Lion Tamer who has kept some of his Lions. a few nights each month, he sets up Lion Bait fights and invite a group of low-lives who enjoy watching dog fights and cock fights. in this Lion baiting, the Lion is forced to fight against a pack of four dogs. But, what the Lion tamer doesn't know is that there is an RSPCA undercover worker who is taking pictures throughout the fight.
In the morning, the Lion-Tamer is arrested, the Lions saved and given to zoos or released in the wild.

Circus Within
During the Night, when the gym is shut and the staff have gone home, a circus springs to life, bringing dangerous animals withing the gym. dangerous to mice. This circus is for mice, and these dangerous animals are cats. On this particular night, one of the cats brakes free and starts to catch the mice. the 'Lion-Tamer' (or Tabby-Tamer) is injured and a Tabby-Tamer in training (or the Tabby-Tamers son) has to rescue the circus and put the cats back in their cages, meanwhile, an employee walks in forgetting his house keys and photographs the whole thing, but is called a mad-man.
