My AMF/Bowlmor center only oils in the summer when there is a league bowling that evening. We have a small mixed handicap at 7 PM Thursdays, on one side of the house; on the other side, at 9 PM, is a singles league. This past Thursday I learned that the house refused to oil for the singles league because the house s not making enough money on that singles league. They said that if they oil, they would be losing money. The house sponsored the league and the past few years that league covered 24 - 30 lanes. This year, I think it is a lot smaller.
I watched that league for a few moments as I was leaving: even higher speed bowlers' balls were hooking in the heads.
And so it goes.
