I recently moved to the UK (in london at the moment) from Sydeny, Australia and have not played any 'ball in over a month.
Might have to come down just to see how rusty I am.
yep should be fine, plenty of guys there walk/get the train in straight after work, as long as you carry your marker responsibly, in a bag disassembled and unloaded, (or partially disassembled and socked) you should never get any trouble from the cops anyways. Obviously if you brandish your marker in any way or take it out of said bag in a public place then Tower Paintball cannot be held responsible for you getting shot by real bullets lol !
.......Of course you would have to be pretty stupid to do something like that
