Greetings or Extortion?

During this Chinese New Year period, you will see or at the very least hear the roaring drums and piercing clanging of the cymbals.

Some of them were invited by the business owners or homeowners to give their premises a roaring start to a brand new lunar year. They would then be duly rewarded with a BIG angpow.

BUT I noticed there were some of them who were NOT invited to the business premises. The team, I saw, was wearing bright coloured baggy trousers with off-coloured t-shirts trying to distract me from their unkempt hairs. They sort of hang around banging their drum placed on a trolleyand wriggling the lame-looking "lion" at your premises UNTIL an angpow was handed over to them...
