But surely someone within the store has one or two pieces ready to sell to tourists. This kind of "dirty" selling used to happen along Kowloon Tsim Sha Tsui area few years back. As tourist return home to discover what they thought they bought turned out to be something else. I gathered this was one of those cases, to catch the unexpected. Since the store has now closed down and hard to track down these "staff", could have left already.
