High scores take precedence over "a fair shot". I don't care what part of the country you are in this is standard fare. Unless you are the only game in town you pretty much have to make the shot easier to keep the doors open. A house could get away with being 10-15 pins lower than the highest scoring house and, as we know, there are some bowlers who actually cherish a more difficult and challenging pattern, but they make up a much smaller percentage of paying patrons.
FWIW, the league I bowl in put out a much more difficult shot on Monday night, but the rest of the leagues get the easier house shot. Currently, out of 52 bowlers, only 3 are above 200. I'm at 192 (make that 191 next week) and there's only been 1 700 shot in the first 9 weeks and the highest game is 268. But there are no mumblings and complaining because the league asked for the tougher shot instead of the ridiculously easy shot we had last year. As I told many people, when I can average 223 only bowling once a week, it's easy. I, too, welcome the challenge. The problem is my brain shuts down after 2 games. LOL
