unusual cultural custom

i think most unusual cultural custom
which ive ever seen is "eating with hand".

i do eat with my hand when i eat pizza,
but i dont really eat with it except pizza lol

coz i think its kinda hard to eat and
dirty to eat with my hand :(

maybe its kind of religious matter and
we japanese might be seen we have
weird culture too, so i wouldnt interfere.
but how do they eat soup?
or they dont eat soup?


i wanna know more about each countries
variety of unusual cultures for me! :)
