What’s the most interesting local custom you’ve encountered?
In Nigeria, if you are wearing a hat or any form of headgear, and you enter a premises, there is no obligation to remove it. While in England, it’s usually customary to remove your headgear. On UK television you hardly see any anchors wearing a headgear but fairly common in Nigeria, if a Nigerian attire is worn.

In America, the customs are opposite for the military (must have on outside) and peasants (must remove inside/never eat with)
