I've talked to everyone I could possibly talk to, I think, and I still haven't gotten my first inventory item. Help please?
perhaps this helps you a bit:
Go to sushi vendor, talk to him -> he is distracted, but not that much
Spoiler
When he has the cleaver up and tries to get a good shot, talk
He cannot sell this piece of fish anymore and discards it
Rest is obvious, if not, ask again for help
