He's trying to get his cue fixed not lectured by Capt. Obvious. Hope you never say something like this within earshot of a po'd player. You may not like what follows.
I've said it within "earshot" of every pool player I ever saw doing that ever since I first started playing pool. I worked in a pool hall as a kid and had to fix the cues. If you did that with a house cue, you were shown the door.
If you had your own cue and slammed it across the table you were thrown out, too. Not for slamming YOUR cue, but for slamming it into OUR table.
I've seen all kinds of cues broken during the time I've played and I just laugh at the fools who can't control their temper and take it out on their equipment.
I've played pool for over 50 years and gambled at it and have never, not even once, slammed a cue, thrown a piece of chalk, or anything else when I screwed up something at the table. I may have said a few choice words while I was going back to my seat, but I didn't destroy anything.
