Most post offices will do it, I think. I bought dollar notes in one a while back without any difficulty. But yeah, it’s not really a business banks would want to be in; if you’re doing it honestly it’s not very profitable, and it can be quite… money-launder-y. Best bet for non-eurozone tourists would be to use a neobank (Revolut etc)/pseudo-bank (Wise etc) that offers fair FX rates, and then use an ATM.

If your home bank isn't too nickle and dimey and is not super tiny, you can probably use ATMs to get cash in foreign countries at decent rates.

You might do better with something FX oriented, but the difference might be small enough to not care.
