Huge Slide saves in our league tournaments, though not illegal, are highly frowned upon, since we are playing on the host collector’s machines. However, when the host slide saves his own machine during the tournament, do you think I am gentle and curt with my slides from that point on? No. If the host abuses his machines, then I respond in kind with my save efforts. Bang backs and death saves are not allowed, but slide saves, depending on how violent they are NOT, are tolerated.
If I am paying to play, then the only referee is either the bartender or the arcade worker flunky watching me or Bob. And if Bob says its ok, then its OK. I am competing with the owner/op to play as much pinball without having to pay for it. If my slide save loosened up the leg bolts a little bit, and scratched the floor, well the owner got a buck out of me for 3 balls which cost him nothing, maybe he can use a little bit of that dollar and pay some flunky $10 bucks an hour to rerubber, clean, wax, and retighten the leg bolts, oh and throw on a new set of leg levelers on the feet once in a while, they cost all of a couple of bucks. A coat of wax on that floor might help with the scuff marks.
