One funny thing we encountered in London was the sheer number of shell game scams. Over a dozen on one street approaching Westminster alone.
They all had the exact same hustle. Two guys running the scam. A lady with dark dyed hair, long black eyelashes, and a dark coat pretending to watch and trying to gather a crowd. A faker in a white tshirt “winning” money.
They were all dressed pretty-much the same, arranged the same, had the same pitch, etc… Clockwork.
