Actually Dave, paid twice... In the first time I went to the cinema with free premiere tickets... The two others were to amuse the girls... ok, I bought 4 tickets... two for each session. But I had benefits from that torture later at night... When I pissed in the theatre I just slid a little to the front, adjusted the position and sent it... I was the only one in a range of three or four rows of seats. No problem with disguising there. FSogol, it's not a matter of seeing a urologist, it's a matter of overloading your bladder...
What, it's not manly too need to urinate - "Real men can hold it!" ? If you're watching Titanic, or any period movie, pretty much you can take a piss break at any time. Nothing's gonna happen. Plus you know the frikkin boat's gonna sink....
That's why I didn't bother going out during that 10-hour-long on-screen torture... Went to a pee, puffed a cigarette and got back... no big deal about how long I stood outside. Good thing is that I saw DiCaprio freezing to death 3 times... oh joy! Kate Winslet was misplaced there... poor her... it was indeed a Blockbuster and helped her career, but she deserved a better film to get to be known worldwide....
