Look, there are many times where you'll get commitee members or centre employees bowling in their leagues. Wether you have a secretary, president, vice-president or whatever, you'll fine 99% of the time they're in the league too. It's not uncommon thats going to happen. As long as they pay their fees and dont BS around by getting 200+ average bowlers as roving reserves and pitting them against you, I dont have a problem with that.
There's a league I bowl in where half the time most bowlers do not show. Problem is, its a guaranteed league and they must pay their FULL fee. The best thing to do is get a reserve in for that paying bowler, its only fair in that way. But for the opponent/s it isnt. But that's getting off topic now...
In the league I mentioned above, there has been ramblings on about one of the employees (or in this case the person running the league) has moved lanes to suit him. Not a good idea when your opponent reads the lane schedule before the match and finds that they're not on the crappy lanes of 23&24 and now have moved to the mpst consistent lanes of 13&14. Makes you wonder when it happens a few times in the season...
