Carlos:
In the shortest way possible, many bowling center proprietors, generally, no longer focus on the league bowler as one that draws high profit margins anymore. Their focus has changed in the past two decades.
I find many bowling centers becoming Family Entertainment Centers (FEC's), or traditional centers with an emphasis on food and beverage. The clientele for theses FEC's are completely different, including birthday party goers and groups of individuals who go to the bowling center to drink. Attendance and profit margins for drawing these customers are generally higher than league bowlers. Therefore, providing player services like pro shops and consistent lane conditions are less important in the modern business.
I remember reading the online reviews for the bowling center that housed the shop I was working for. A common complaint from these FEC-type customers were actually how the lane oil got on their clothes. Yet, after reading that, I was actually thinking how the GM/proprietor to lay down more oil, at least for the league bowlers. The proprietor has to choose who would be readily equipped to keep them afloat.
Hopefully, if you still love bowling, you will have to adjust and rely less on technology because of the reduced amount of oil on the lanes in these FEC's, which clearly cater better to open play bowlers' needs.
If this trend is something you don't think you can deal with, you may want to consider another hobby that may not present you with such frustrations, or consider bowling in a market where league bowlers are still the focal point of the proprietor.
Best of luck.
