I’m quite sure we had this identical topic discussed in a thread a year or so ago. As with virtually all things here, you’ll get a variety of opinions.
Do I think it’s showing disrespect to the equipment, yes, but as long as it’s not my table and the promoters encourage it, I’m guessing it will continue.
I just wonder if the future buyer/owner of this tournament used table would approve of this or is even made aware of this? I doubt it.
I could see a player's weight doing damage to the rails and subrails as he pulls himself up, but I'm curious what damage you think would be caused to the table frame or slate itself (not being snarky, I don't know the answer)?
