No joke, bro.....leave that place ASAP. It's not like it was an important career job or anything.
"There are a million jobs in the world....you're bound to be qualified for one of 'em."
After putting in your notice (always do this if possible...it can screw up your nice coworkers lives if you just take off), you should go back to the manager and explain to that bully that if he ever lays another hand on you, or another employee, he'll be sued with the golf course named as a co-defendant in the case. This would most likely cause his termination or at least further the cause.
Then, explain to him that after the suit, win or lose, you'll take a 9 iron to his Adams' Apple.
Or, just learn from all this, be the bigger man, and walk away.
