You are describing the last place that I drank and tended bar. Main difference being that the police were never called but for the occasional overly concerned outsider but if/when they arrived nobody would acknowledge their presence (questions were met with louder juke box volume) and they would just leave.When I was a young man, they used to have bars without bands, didn't serve food, unless you counted the fifty-three year old jar of hard boiled eggs sitting on the bar as food. They had a card room, and pool tables, both of which guaranteed that if you hung around long enough you would either see, or be in a fight before the night was finished. You should see how much blood can fly out of a guys head when struck with a cue ball, or cue stick. I don't think they have those kinds of establishments anymore, but they used to be just the ticket for an ambulance ride, a ride in a POLICE car, or if it was a really bad night, a trip to the morgue. ALL of these have occurred at one particular bar I used to frequent.
Instead of an ambulance, the perceived instigator would get dowsed with a half bucket of cold water to wake them and were given a ride to the local truck stop in the back of a pickup truck. This only happened to somebody after repeated warnings but some guys are born peacocks and they strut more with each drink.
That bar was demolished about 2 years ago and is being replaced with Towne Houses. Another chapter in a drinking life.
