We only have one non-USD debit card at home for an account Mrs. Majuki has, but she keeps next to nothing in that account. Furthermore, she also doesn't like going around making small transactions at random places just to see if DCC is enabled.
Additionally many smaller stores are more okay with customers handling the terminal these days, so I'd expect opt out to be easy there too. Restaurants might be the one exception as pay at the table is still pretty uncommon (but good customer service would prevent most issues).
