Pub with a flat roof was mine based on the one nearest to my house
Also see - "never drink in a pub that needs a bouncer on the door"
Other life rules from my own Museum of Recollections are ...
Never queue for a table in a restaurant, its not your fault they haven't got enough tables and they certainly won't have enough staff to serve you if its full.
Never pay more than two hours of your wages for a pair of jeans or a shirt, anything in excess of that is someone taking the p1ss, usually the retailler.
Never buy a second hand jigsaw if you want to avoid weeks of frustration.
ALWAYS check for signs when parking your car, you're looking especially for small signs thirty foot in the air with red writing on - the ones that the clamping company put there.
