I suggest they ask again, or do what I do and hang out at the store until other people come in and start looking at airsoft guns. Then chat them up and become friends. If your buddy is white, he'll make a friend pretty quickly as long as he states he is Canadian and --NOT-- a yankee.
God damnit those retards gave alot of us other white-looking folk a bad name. But don't get me started on other races of people in Japan... there's two I hate... I'll get into that later.
But yes, tell your buddy to ask again, or hang out. If they haven't already asked, please shit in his pillow-case on my behalf, ok?
