Please list the times you've recently been "inconvenienced" by someone drinking on the tube, and detail the exact nature of the inconvenience caused. Thanks.
How about getting to work and stinking of special brew despite being tea total?
How about getting up from the seat and sticking to it as the alcohol has seaped into your suit trousers, hey just another a few quid down the dry cleaners, no inconvenience there.
How about getting on a carriage after a long days work and realising that it absolutely stinks of special brew and is making you want to heave, and you halfway between stations and somewhat stuck, hey no inconvenience to travel down the carriage, open the window and hold your head there, no inconvenience to have to get up at the next station and move to the next carriage, in the hope that it too doesn't stink of special brew.
