Apparently the ghost craze extends past Halloween. Just check out this shop somewhere near Teo Heng KTV. I think the ghastly screamings of out-of-tune KTV goers prompted some guy to start a Ghostbuster shop.
And it was open at 2a.m. Not surprising, since his customers probably need his services at unearthly times.
Check out his comprehensive marketing in-store. Complete with LCD screen and article reports on his one-of-a-kind service (probably all from LianHeWanBao).
