I'm traveling to the United States for the first time. What do you know about manners in the U.S.? What tips do you have about b

Ivenika [448]

Explanation:

Eye Contact is key. But don't stare

Table Manners : When dining, people consider it not nice for a guest or dining partner to burp , eat with an open mouth.

When you want to refuse something politely say, " No Thank You. "

When accepting say, " Yes Please. "

Always say thank you when someone helps you out ( common knowledge )

When entering/leaving : ( stores, etc..) When the staff or anyone say "Welcome" or "Hello" , always say "Hello" back or it will make you look like you are ignoring them. Same goes to when you are leaving :)

Phone Calls : this one is important because when someone calls you and you start talking loudly or put them on speaker in public, it looks r u d e to the people beside you. They don't need to know what your private life is. I've had this happen a couple of times and its very uncomfortable.
