Customs
Laws vary from state to state, including speed limit, fines and punishment. The age at which you may legally buy and consume alcohol is 21 years.
Tipping
A 15% tip is expected by taxi drivers, bartenders, hairdressers and waiters, but don't tip in fast-food or self-service restaurants. In expensive restaurants or for large parties tip 20% of the bill. It is normal to tip staff staff such as valets and porters in hotels; this is discretionary although a minimum of $5 is expected. Most services are customarily tipped if the service is good.
