However, again, this can easily spin out of control. Recently I have had to travel a bit nationally in my work and an unnerving custom has developed in the company where people on national business trips bring back something edible for the whole office to try out from their destination. I just simply refuse to do this, it's bad enough that I have to go to stupid Hiroshima for a stupid appointment which I didn't particularly enjoyed or even wanted to go to in the first place and the only place I saw except for taxis and train stations were the meeting location. But I'm not gonna spend 1000~ yen of my own hard-earned money buying snacks for people who didn't really care about it anyway. This was the way things used to be, only controlled gift-giving within the office.
Somewhere in the company during my departure a paradigm shift happened and people started buying stupid (they're usually not good to begin with) snacks from all over the place and placing them in the cafe space. But I refuse to play along, I just don't bring back anything and I'm hoping to create a counter-culture to stop this excessive snack purchasing.
The exception is when I've been on overseas business trips since the general image in most people's minds seem to be that that's all fun and games, so to somehow lessen the envy a little bit I usually bring back some local snacks (most recently Crocodile and Kangaroo jerky, which for some reason remained uneaten for weeks at end, the ungreatful pigs and sows...).
