I agree. Apologizing for slop is ridiculous. If you really feel like it's unfair that you missed and the ball went 3 rails into another pocket, pick up the cue ball and hand it to me. Otherwise, just be glad you got a roll and keep shooting. If anything, a sarcastic "yes!' is appropriate in that situation.2. Apologizing when something works out for them. There is chance in this game, get over it already. I was watching the ladies play on ESPN the other day and the amount of "sorrys" was really getting on my nerves.
To me this is just acknowledging that other people are going to go nuts over getting a bad roll. Shit happens, move on. If people didn't get so bent out of shape over "slop" nobody would need to be apologizing in the first place.
If I get annoyed at the table, it's only going to be at myself. There's nothing anybody else could do at a table when it's not my turn that's going to cause me to care even the least bit (other than screwing with the equipment).
On the other hand, I do think that it's okay to acknowledge your opponent's misfortune when you miss a shot you intended to make and leave them hooked.
