How to Behave In An English Pub

If I ever go to England I plan on studying HOWTO: Drink like an Englishman, in an English pub:

when being served, your order should end with the word please. Once your change has been returned, a thankyou is required. Don’t embarrass the barstaff by leaving your change; if you want to tip then offer to get the bar[wo]man a drink.
Remember, gentlemen drink pints… Ordering anything other than a pint as your first few drinks will have you labelled as a big girly poof with limp wrists.
