Manners are an important part of British culture. Some key British manners include queueing politely, using "please" and "thank you", covering one's mouth when coughing or yawning, shaking hands upon introduction, and saying "sorry" when bumping into someone. Basic politeness is expected in interactions. Meal times in Britain typically include breakfast between 7-9am, lunch between 12-1:30pm, and dinner or supper between 6:30-8pm. Traditional British meals include a full English breakfast and Sunday roast dinners.
