I've only been cut off once.
Mildly funny story actually. Travelled to Melbs for a fun weekend with a couple of mates. We went to some hidden underground Japanese place called Yu-u for dinner (google it) and drank bucket loads of sake and got really merry.
On the drunken walk back home across town, we found a small bar that was still open and they happened to have a bottle of Bacardi 151 on the shelf. Righto, three shots ordered! I drank the shot, had a chat and a laugh with the the bar guy (who was the only worker in the whole place) and went to take a piss. As I was walking back from the toilet the bar worker came up to me and said 'you all have to leave. NOW.' I thought 'what the hell happened in the 45 seconds I was gone?' and I looked over to my friends out the front, then to the giant pool of vomit on the floor in front of the bar. Oh. One of my friends clearly didn't like the shot of one fiddy one.
So we were almost back at our hotel still walking, and we wandered past some underground punk bar. All of a sudden, some dude I've never seen before comes running up to me yelling, 'GARY!!!! Gary its you!!! How the **** are ya?? HEY EVERYONE ITS GARY!!!!' (I'm not Gary.)
I was so hammered I was like, 'hey **** yeah I'm Gary, whats up??' and all these guys and girls come running up to me saying '**** its Gary!!! So great to see you!!!! Lets get Gary a drink!!'
My friends were looking at me saying 'Gary??' but they went along with it. The unknown people dragged me down to the bar. I ordered a jug of pale ale at the bar and as I said 'ale' I slammed my debit card down on the bar and it broke in two. The woman had barely poured 200mL into the jug when she looked at me and said 'you have to leave'. All the unknown people were saying 'nooo Gary noo!!' Staaaay!' but there was no getting any alcohol from that place.
We walked to our hostel on Elizabeth St. The hostel has a bar on the first floor, and our room was on the 5th or 6th floor. We tried to go up the escalators to go through the bar to our room but the bouncers thought we were just drunken people looking for another drink (possibly guilty as charged) so they wouldn't let us in. No problemo, we used our swipe cards at the lobby next door to get in and up to the bar via the lift. We then thought it would be funny to leave the bar, so the bouncers would see us and go 'hang on, we didn't let those dudes in!!' so we left the bar downstairs via the escalators and said goodbye to the bouncers who looked rather quizzical. We then thought it would be funny to do this about 12 more times. Up the lift, down the escalators to wave goodbye to the bouncers. By the 8th or 9th time they said ENOUGH!! and threatened up with physical violence. Good time to go to bed. And there's my drunken story.
There was another time we stayed in the same hostel, we went to the Tool concert and took bucketloads of acid, and when we were back in our hostel room still tripping balls a half naked wet Japanese man who had come from the showers walked in and freaked us all totally out, (he was assigned the wrong room by the hostel staff) but that story's for another day.
