Why do some men flush the urinal before using it?
Is it just me, or does this process make no sense?
Are they afraid of splashback? They'll get it anyway. Not that much difference to your pants whose urine it is.
I can see the idea using a toilet. You want to make sure the flushing system is fully operational before you add to it and potentially make the problem worse. "Sorry plumber! Yeah, I saw the pool of urnine in the bowl, but really had to drop a load off, and didn't think it would hurt. What, no, I didn't think to check if there was a problem..."
But a urinal is basically just an open pipe, many models have no stagnant collecting pool at all, so only need a sporadic flush which acts like more of a wipe-down. (Related: This is why some establishments keep ice cubs in their urinal basins rather than rely on drunks to remember to flush)
Why do some men waste the water before letting go?
