Booze on the tube

Inspired by other thread but think it deserves one of its own.

Kept my beer inside my plastic bag most of the time since the ban but don't even bother with that anymore. Does anyone NOT drink on the tube?

There's fuck all penalty for being caught either way, an extra pre-drink or two is nothing. I tend to stick to those mixed g&ts if I'm day tube drinking but does anyone actually listen to it as a whole?
