Well, sometimes you've just got to be
that hardcore to win. You think someone like Fatal1ty can afford to stop fragging just to use the washroom?! Please... Time is money my friend, and some of us have
very valuable time.
EDIT: Now that I think about it, assuming $1 per diaper and 5 minutes for a washroom break, then if you make over $12/h, it's a net gain. Interesting, because that's not a lot of money. Although, it only applies when your wage is based on the quantity of work, but there are many jobs that fit this profile. It also applies to jobs where the cost of leaving one's workstation is excessively high, like astronauts, but I've also heard of truckers, travelling salesmen and Chinese train passengers doing the same thing. Of course, one must consider the social and environmental costs as well. Then again, 10% of the population is incontinent anyways, so the first is probably fairly low in fact. Next, the latter issue is resolved with cloth, and also saves the water that would otherwise be flushed away. I can find little rational basis against the practise, on the whole.
Therefore, I must conclude that I am irrational, since I would never do this in a million years. Moreover, the internet has filled my mind with useless and disturbing knowledge.
