Well, it certainly depends. I'm not expecting McDonald's to send me a thank-you note. I was talking in generalities, not specifics.

I frequent a local store that sells boutique art supplies. Natural paints and that sort of thing. They are very customer-focused, and while hand-written thank-yous aren't something they do, if they started doing them I wouldn't be surprised. They know and appreciate their customers, and were particularly good during COVID, as the owners had health issues that made them concerned. They survived, partially due to their customer service, which included direct messaging as required to make sure people were able to shop and get their purchases easily and safely.
