One thing about taxi driver in Hong Kong, you rarely see a cab without a few mobile phones mounted on the dashboard. The taxi driver here loves to talk and if he's not talking to the passenger, he will be on the phone with his friends or whoever. Sometimes, in-between chatting with you, the driver will switch to talking on the phone and as he is on the earpiece, it can leave the passenger momentarily confused.
Just the other day, I boarded this cab with 5 mobile phones in front of him. This is really quite common and it somehow reminded me of the days when I was a bank dealer having 4 to 8 computer screens on my desk. I suddenly took a peek to see if any of his screen is showing stock prices. 😅
