Apparently Fujimoto really liked sushi. Combine that with the fact that living in Japan, you're going to be able to eat sushi at some point in your life, it was only a matter of time until he found out he really liked sushi and wanted to become a sushi-chef. For all we know, there had been several "close calls" before this one, his parents maybe wanting to celebrate a special occasion with sushi, but then changing their minds. If his friend hadn't treated them, he would've probably had other opportunities to taste sushi and find out the same thing.
