But honestly, I've seen actual loansharks of the shady chinese community in action and it's bad...
Say a hard gambling cook at a restaurant goes off to play mahjong in a gambling parlour in chinatown, then gets tapped out of his own money, he then wants to "borrow" some, hoping to win his own money back.
Shark will oblige, usually a minimum of £5K, and the term usually runs for 12 months.
The Pay-Off works like this:
The cook will pay back anything between 2% - 5% of the total loan amount every week as interest and at the end of the year the original £5K on top too.
And if the gambling urge still has a hold, then there will be other loans and as a result, you get some restaurants suddenly changing names and stuff...or cooks/waiters/etc. just disappear.
