This must be cultural because for me it's much easier to buy e.g. some mackerels and fry them than to make sushi. In fact, in my family grilling fish is literally one of the things we do when it's near dinner time and we haven't anything prepared (go to supermarket, buy some fish, grill it, eat). While sushi is something I haven't even tried to make because it seems to take a lot of time and effort (I do love to order it when I eat out).
