In such a large country, filled with so many diverse groups, business practices may differ according to each state, however rarely to any large degree. The East Coast is traditionally more formal than the West Coast, however in states such as California dress code and conservative appearance are as common as they would be in New York. Punctuality is important throughout the country and it is considered rude to be late for a meeting. Gift-giving is uncommon as it may be construed as bribery. Appropriate titles (Mr, Mrs, Ms) are used upon introduction and until otherwise stated. Americans favor politeness and greetings of 'Hello' and 'How are you?' are often expressed with sincerity. Business hours may vary in each state, but an 8am start and 5pm finish Monday to Friday is the most common with an hour over lunch.
