 The scene in the Chinese restaurant where the woman in the  background reacts strangely when the lid is lifted off the serving  tray is a reference to a Czech TV commercial. In it, a couple goes  into a Chinese restaurant with their pet dog and tell the staff to  take care of it. Apparently something is lost in the translation as  the beloved pet is taken care of by being cooked and served to them,  producing the same horrified reaction from the woman.
