With all due respect Fran, I have to take 80 mg of Lasix and 25 mg of Spironolactone daily and the effects last for about 8 hours. The urge to urinate comes out of nowhere and demands that I get to the bathroom RIGHT NOW, or else! There are other conditions exclusive to males such as Benign Prostatic Hyperplasia (BPH) (which is actually quite common among older men) that produce the same effects--an uncontrollable urge to urinate.
Now I don't know if any of that applies to the gent in question, but in any case I don't see it as a big deal. Most of the time, I have just enough time to tell my opponent, but there are times when I just have to drop everything and run to the men's room before things get messy...it's not a shark move.
Perhaps it would be better to whip it out and pee a quart or more all over my opponent, the chairs, the table, the rug and any spectators? For some strange reason, I don't think any of them, not to mention the owner of the pool hall, would appreciate it!
