Tradition, Maybe!

In case you can't read the sign, it says - Please BOW BEFORE you enter your backroom.

Quite obvious that this sign is put up by a Japanese company although I do not understand why they request that their staff bow before they enter the backroom. Who or what are they supposed to bow to? The Gods of Supplies? The resident ghoul of the storeroom?

Anyway, for the few minutes that I stood there trying to sneak a shot, a few staff walked in and they seem to ignore the sign on the door. Oh well, I guess rules are meant to be broken, huh?
