On the inside of buses in Leeds you may well see a sign that says “Hands up if you know how to catch a bus – Just hold out your hand to let the driver know you want the bus to stop”. Please note that this is on the inside of the bus - upstairs in fact. So if you don't know how to catch a bus how did you manage to er, catch the bus you're currently on? And do you have zero observational skills? Have you not noticed what people do at bus stops the world over? Or are you a moron thirsty for validation of your recent bus catching behaviour?
What it doesn't say of course is that unless you hold out your hand the bus driver will have no clue as to what on earth that line of 25 people are doing waiting at that pole on the pavement with 'bus stop' written on it - and he'll cruise past.
