I need a worker's visa to do that. It's kind of funny actually, because if you're there as a tourist visiting a friend and you just so happen to cover for his/her shift at 7-11 one day, YOU COULD GET ARRESTED because you worked while not having the correct visa. I think this is especially the case and you could get barred from the country if you receive payment for your time behind the counter.
>hey onee-chan, I have to go home for a bit, will you cover for me?
>what? sure, ok.

yabai.
