yup, good points.
In my dad's pool room back in the late 70s, I'd tell folks to not put drinks on the rails, or cigarettes, etc. I worked there after HS, but usually was cutting class to get there earlier. I was like a hawk. Most complied. The ones that didn't, and told this skinny kid to bug off, I'd just say well, I guess I will let Phil know you refused. He was one of my dads partners. Those who knew Racetrack Phil quickly removed whatever they put on the rails and apologized profusely, so I would not call him. The folks who have not yet met Phil were about to find out the hard way.
Phil was not what you would call "customer friendly" to anyone that didn't follow the rules. He was a hot tempered dude who looked like a boxer and had a permanent scowl on this face. He always carried a gun, concealed, but he never left home without it. 1970's Chicago had some of the toughest gun laws in the country. Concealed carry? Not unless you had a friend on the City Council or your dad was a judge, otherwise, no chance.
But, the only time I saw him pull the weapon was when some dude was trying to leaving without paying his $10 tab. He literally flew over the counter when he heard what was going on and the guy was trying to walk out. He grabbed him by the back of the shirt, put the gun to his head and politely asked, "going somewhere Jackson". I'll never forget that as long as I live. The customer was pissed and asked his question, "you gonna shoot me over $5". Phil said, "No i'm gonna shoot you over $10". It was quite a Quentin Tarantino esque moment.
He walked him back to the counter, told him to pay me and the guy threw out a $20 bill on the counter. Phil then asked, "is there something else you need". The guy said, "yeah, my change would be nice". Phil said, "you're a big tipper, now get out". I never got a $10 tip before, lol
