You know the feeling. You’re busting for a piss, doing the cross-legged dance of bladder pain and plucking up the courage to sneak into a random pub to relieve yourself. Wouldn’t it be nice to know if there was a place nearby that didn’t mind you using the facilities? Well we’re very grateful to Who’s Jack for bringing us this Tube map with nearby free comfort stops. PHEW! Never be caught short again.
