Buddha, yeah, probably because you won't be there. As for the rest of us, the idea itself is insulting to say the least. What it attempts to accomplish may be a somewhat worthy goal, that is, to promote safety and decorum. The logic behind it, however, is pathetically narrow and unfortunately commonplace of the rest of society which paintball usually provides relief from. In short, it's saying that we can't drink responsibly and are drunken low class jackasses, so we should have a leash around us to keep us out of trouble. Rather than acknowledge that we're human beings, and that there are always a few people who just need to be dealt with on an individual basis BECAUSE THEY, NOT THE DRINK THEY WERE HOLDING did something wrong, whoever responsible for this idea decided the best thing to do is to look down their noses at everyone and assume them to be peabrained irresponsible morons and treat them as such.
And to the "we don't want the kids to see that" people, it's you that need to grow up. Withholding reality is like putting a hand up against a seawall in the middle of a hurricane: yeah, you'll maybe hold a cup or two of water back for a little while, but it just makes it gush harder when it breaks and you'll look like a moron for trying.
