Friendly Fishmonger
In my encounters with people I meet when I go shopping for fresh produce, fishmongers are the friendliest.
My regular fish stall at the morning market is a pickup truck with loads of fresh seafood. According to the fishmonger, he gets his seafood fresh off the fishing boats operated by his cousin and a close friend.
He never seems to stop talking or singing. Good salesmanship but honest. He finds time to share his food recipes and proud to show off snapshots of his cookery skills.
My fishmonger is very friendly but he would get extremely irate if ever anyone doubts the freshness of his seafood. He has no qualms telling the person to just leave and go elsewhere. His equally friendly assistant is highly versatile with his knives. He is most willing to fillet, dice, butterfly or whatever manner of slicing of your fish purchases.
