Beware of scums in Bangkok

Yeah,i am still in 1st of April.
I have no choice because too many things happen today.
There are many scums wonder around Bangkok.

These scums do not cheat your money directly, but they will first approach you by themselves and be very friendly to you. Then will show you the direction and provide you with the information. Next, they will influence you to visit some unnecessary places which is expensive. They are so kind that they even call a transport for you which is usually a 'tuk-tuk'. When they do this, you will be too shy to reject their 'kindness' and end up spending money and time on useless places.

We also encounter one of these guys in the first day. Being so naive, we actually believe what he says and spend 1200 Baht (RM120) on an useless canal drive for one hour which cause us to over budget.
