Americans are outgoing, warm, and straightforward, and they do not adhere strictly to formalities. Their customs and etiquette have many unique aspects. The United States is a country with a strong sense of time; various activities start at scheduled times, and being late is considered impolite. Arranging to meet with Americans is simple; a phone call will usually result in a happy agreement to meet in a short time. Americans also have a custom of reciprocity in hospitality, but they are averse to accepting overly extravagant gifts. This is partly because Americans do not place much value on the intrinsic worth of gifts, and partly because the law prohibits excessive gifting. Souvenirs, artworks, and fine wines brought from one's hometown are popular gifts among Americans. Except during holidays, it is generally unnecessary to bring gifts when invited to an American's home for a meal. Tipping is customary in American society; a tip is expected for all service-related activities. For hotel doormen, room service, etc., a tip of no less than $1 is required, and a 15% tip is customary when dining in restaurants.
When Americans host a meal, it is often in a business context and typically takes place in restaurants or clubs, with expenses covered by the host's company. Only close friends and family are invited to dine at home. The variety of food in the United States is vast, differing by region and ethnicity, with hamburgers, hot dogs, pies, donuts, and Kentucky Fried Chicken being globally popular. However, home-cooked meals served to guests are economical, unpretentious, and informal. A typical home meal features a long table with a large platter of salad, a large platter of roasted chicken or meat, various cold dishes, a plate of fried rice, a plate of bread, as well as desserts, fruits, cold drinks, and alcoholic beverages. The host and guests sit around the table, and the host will say "please"; everyone then takes a plate and serves themselves from the dishes they prefer. After finishing, they can help themselves to more food, chatting freely while eating.
Americans consider inviting guests for a meal, drinks, or a weekend at a country villa as a way to build friendships, and they do not necessarily expect reciprocation. If the opportunity arises, inviting the guest to their home for a meal is sufficient. After the meal, guests should express special thanks to the host, especially to the hostess.
