Maybe the water fountain far off was broken and he had to filter his own urine to quench his thirst, that takes time. I hear drinking one's own urine can be done and may even have therapeutic effects, but haven't experimented myself, just seen about it on those survivor man shows. I don't know if it would be against USTA or ITF rules, like blood doping or prohibited drugs, but I guess they could do a urine test for it. Now that would be ironic or wouldn't it. Maybe this belongs in it's own thread? I'll check with the mods.
BTW, where can I get some of those Babolat Roddick USO, red white and blue shoes with the stars in 11.5 or 12's? They are out everywhere and I'd like to have some for President's Day or Fourth of July.
