A less urban but not rural part of California.

I do tend to shop at low-margin places like WinCo Foods. There's also an auction house I buy big ticket items from. Both charge credit card fees. I've never seen a gas station anywhere in the US not charge extra for credit cards, and most also charge extra for debit cards. The DMV also charges a fee. I don't know if Grocery Outlet charges a fee, but I do shop there too.

Also, pretty much every recurring charge I have, e.g. from T-Mobile, Comcast, and my water supplier and mortgage processor all charge credit card fees, if I use a card instead of ACH transfers.
