First off, I am not sterotyping all bowlers so save your breath. As Kevin says during hid dining reviews this was my experience, yours may be different.
I worked in a bowling alley for a while when I was in college and it was probably the worst job that I ever had. Boot Camp was better.
There were some good folks on some of the leagues but on the weekends I had to put up with a bunch of drunks, people trying to steal the ugly bowling shoes, throwing the bowling balls halfway down the lanes. Idiots.
I saw more men and women cheating on spouses then I ever have in my life. Some of the guys would ask me to cover for them if their spouse would call looking for them and was asked by many women to do the same.
I have literally seen a group of ladies talking by the desk in a group deciding on what bar or club to go to and watch them pull off their wedding rings and put them in their pocket.
We kept a uniformed off duty policeman as security a good portion of the time when the place was open. I have had many people escorted off the premises with the guy in the group threatening me as he was being hauled away that he was coming back for me at closing, (they never did although I was hoping a few of them would be "brave" enough to show up. Some I was concerned they would be back with a shotgun)
Some of the regular bowlers who was in leagues (I didn't say all so don't start yelling at me) would constantly b.. errr complain about something no matter how well the place was maintained. They sucked at bowling so they would whine about not enough oil on the lanes, too much oil on the lanes,etc. We poor desk clerks were constantly getting griped at.
It may have been the area we were in and I know I probably did not notice the good folks as much as I saw the bad, but to this day I get the creeps and pretty ticked off just driving in front of one of those places.
YMMV
