In the United States, there are certain manners and social norms that might not be explicitly taught but are expected in various situations. Here are some manners that can be helpful to know:
Tipping: In the U.S., it's customary to tip service industry workers such as waitstaff, bartenders, taxi drivers, and hairstylists. The standard tip is usually around 15-20% of the total bill, depending on the quality of service.
Holding the door: It's considered polite to hold the door open for the person behind you, especially in public places like stores, restaurants, or offices.
Saying "please" and "thank you": Using these simple expressions of gratitude is a fundamental aspect of politeness and shows appreciation in various social interactions.
Personal space: Americans generally value personal space. When talking to someone, maintain a comfortable distance, and avoid standing too close unless it's a close friend or family member.
Making eye contact: In conversations, making eye contact is considered a sign of respect and engagement, but it's essential not to stare excessively, as this can be uncomfortable.
Introducing yourself: In social gatherings or professional settings, it's polite to introduce yourself when meeting new people.
RSVP: When invited to an event or party, it's customary to RSVP (Répondez s'il vous plaît) to let the host know if you will attend or not.
Offering to help: If you're a guest in someone's home or at a gathering, offering to help with cleaning up or other tasks is appreciated.
Chewing with your mouth closed: While this is a basic etiquette rule, it's essential to chew food with your mouth closed during meals and avoid talking with a full mouth.
Not discussing sensitive topics: Avoid engaging in heated discussions about politics, religion, or other sensitive topics in casual settings to maintain harmony and respect diverse opinions.
Saying "excuse me": When trying to get someone's attention or passing by in a crowded space, saying "excuse me" is polite.
Not interrupting: It's considered respectful to let others finish speaking before contributing to the conversation.
Using utensils: At the dining table, use utensils appropriately, such as forks, knives, and spoons, and follow the general American dining etiquette.
Saying "bless you": It's common to say "bless you" when someone nearby sneezes, as a courtesy.
Not discussing income: In general, Americans tend to consider discussing personal income or financial matters impolite, especially in casual settings.
Remember that manners can vary slightly from region to region and from one social group to another. The most important aspect is to be respectful, considerate, and mindful of others' feelings in different social situations.
