Hit with DCC at a small SE Asian restaurant far off the tourist path in Dubai today, where westerners are very rare. I entered my PIN, handed to the unit back to the server, who seemed as taken aback as I was, handing it back to me, "Do you want Dollars?" Screen gave both the Dirham price she'd entered and a Dollar one (of theirs): push green for Dollars or yellow(!) for Dirhams.
