You've got more life experience than I have. I've never been escorted out of a bar. Of course I've never told them that a commercial name-brand product they served me was "crap".
lol
Maybe you were not aware of the problem with guinness kegs. They go bad much easier than any other kegs in a bar. The are not pressurized with CO2. They are pressurized with nitrogen. If they don’t serve several pints per day every single day, the beer in the line from the keg to the tap will go bad and the “infection” will spread to the keg and spoil the entire keg. It is common for a keg to go bad in a bar that doesn not serve enough of it to keep the lines clear of “infection”.
This is why most bars do NOT have guinness kegs and do not offer guinness on tap. You have to watch out for the bars that are marginal...the bars that WANT to have guinness on tap but do not serve enough of it to keep their lines clear.
Thats my beer course for the day, I guess. Carry on.
When I was an 18 year old young fairly tiny lady I was removed from a bar bodily by two big guys carrying me off the ground, by my shoulders out the door. I was a very new pool player and handily beat the owners son at a game. His game was his pride, and he accused me of being a shark. His mom, the owner, had me removed, probably before her son would have hauled off and hit me.
One other time I was removed from a strip joint/bar by the bouncer, who carried me out. A young, zealous Christian I went up on the stage and started preaching to the girls and the crowd. It was interesting because the crowd loved me, not so much the girls, who were upstaged. The crowd booed the bouncer for taking me away. The bouncer was so gentle. He carried me like he thought I could easily break.
