When travelling or working in the tourism sector, you are likely to meet different people of different cultures. Different cultures have different protocols. So it is very important to be aware of such differences so as to deal with people in a suitable way and not to create tense or offensive situations. What is considered appropriate behaviour in one culture can be inappropriate in another. When working with people from different cultures, you need a solid understanding of the norms of that culture.
It would be really interesting if you could share with us any cultural faux pas tourists or foreign people make while in your country. I will be waiting for your comments.
