I know this is possible based on one of the two purchases during my first trip to Chung Yo Department Store. However, since I wasn't physically present at the cashier stand, I couldn't see what key sequence disables DCC completely. This is obviously the preferred option since there is no chance in a moment of weakness to tick the wrong box or for there to be operator error on the part of the cashier.
