That Seems Like A Proportionate Response

I once had a customer who looked pretty young wanting to buy alcohol. I asked to see his ID and he refused to show it; hence, the manager had to come along.

A year or so later, said customer comes back, but I don’t recognize him. He instantly starts yelling at me.

Customer: “You might not recognize me, but I recognize you, you red-haired b***!*”

I reply to him as calmly as possible.

Me: “With all due respect, sir, I see a lot of people every day. I’m sorry I don’t recognize you.”

He then goes off calling me names and starting to threaten me while constantly inching closer towards me until he is right in my face.

Customer: “I’ll make sure of it that you’re scared when you walk the streets.”

He then proceeded to spit in my face and raised his hand to hit me. Luckily, we had a security agent who was fast enough to notice what was going on and intervened, telling me to go to the back so I was safe. On my way back, I heard him yell:

Customer: “You’re dead! I’m going to find you!”

And then, afterward, I found out who he was and why he hated me so much: all because I asked to see his ID.
