don't drink anything before flying

so this is out of chronological order from my last post, but i have to get it out....

flying to providence on friday afternoon, flight's delayed.
first, for over an hour waiting in the airport, then we finally get on the plane.

i sit down, and being i'm in the A group to board (southwest style - if you're there early, you get a better seat basically), i sit in the very front row, aisle seat. about 3 feet from the bathroom.
everyone is sitting down, the attendants are going through the plane making sure everyone is all good to go. i ask the ground crew guy who is walking around if i can take a quick piss..."no", he says,"we're about to take off, and you dont want to be the one who delays the flight."
ok, i hear that so, assuming we're about to be airborne i don't push the issue.

over the next hour and a half (!) while we're sitting on the ground waiting to take off, i ask a few more times, not wanting to be the obnoxious passenger guy, but really having to piss.
the answer each time, is 'sorry, we're about to take off.'

ok. so we take off finally, and we're way up in the sky, and still i can't get up, walk 3 feet, piss for 30 seconds and sit back down.
at this point, other passengers around me are telling me that it's so not cool of them
not to mention (though i am) the freakin' flight attendants are all using the bathroom, passing out drinks etc - talk about adding insult to injury.

finally, i ask the F.A. and she's like, "well, i can't tell you that you can go, but i'm walking down the aisle and my back will be to you, so do whatever you want"

hm. ok, so i get up and go piss, back in my seat in about a minute. after having to hold it in for literally 2 and a half hours!!

now, i understand security and all that shit, but this just wasn't right.

as a kind of side point, the length of the actual flight from philly to providence is 37 minutes.
