Seems like you lack a training in the nuances of British English. We also prefer aubergines over eggplants. Maize not corn. Mangetout not snow peas. We prefer chips to french fries and have biscuits instead of cookies, and jelly babies instead of jelly beans

If you leave the house wearing just your pants you'll get some strange looks. Better put your trousers on first. If you don't mention about fannies we'll return the courtesy and won't go asking you for a rubber in the middle of the office.
