不同的國家和民族，由于不同的歷史，文化，宗教等因素，各有特殊的風俗習慣和禮節。例如，伊斯蘭教徒不吃豬肉，在齋月里日出之后，日落之前不能吃喝；有些佛教徒不吃葷；印度教徒不吃牛肉；某些國家如印度，印尼，馬里，阿拉伯國家等，不能用左手與他人接觸或用左手傳遞東西；在佛教國家不能隨便摸小孩頭頂；天主教徒忌諱十三這個數字。尤其是十三日星期五，遇上這種日子，一般不舉行宴請活動；使用筷子進食的東方國家，用餐時不可用一雙筷子來回傳遞，也不能把筷子插在飯碗中間；東南亞一些國家忌諱坐著蹺大腿；伊朗稱好不伸大拇指；保加利亞、尼泊爾等一些國家搖頭表示稱贊，點頭表示不同意，等等。阿拉伯國家婦女比較守舊，到人家家里作客不要問女主人身體如何；對日本人送禮要注意花式，綠色被視為不吉祥，荷花是祭奠用的，禮品上不要有狐貍的圖案，因為這種動物狡猾，貪婪。不要把菜湯和飯拌在一起吃，因為這是喂貓的方式。在婚禮上忌用離開、重復、多次等字眼，在喜慶場合忌用去、舊、壞了、完了等字眼。若不注意這些風俗，會使人誤認為對他們不尊重或鬧出笑話。新到一個國家或初次參加活動，應多了解，多觀察，不懂或不會做的事，可仿效別人。 Different countries and peoples, as various historical, cultural and religious factors have special customs and courtesy.
