when taking a cab , make sure it doesnt say "Grab" on it. They will go with the meter but once its turned on it starts clicking away and you dont get the 1st Km before it goes from 35 to 37 , it hits 37 even before the car even moves

Happened to me twice today, 1st time was going from Holiday inn sumhuvit to Park Hyatt meter ended up at 73 for , 2.4 km drive

2nd time no choice was by National Stadium and over a dz cabs wouldnt take me with the meter, my luck the driver who said OK was a Grab cab and door closed , meter turned on and it started clicking away from get go

I think to be safe make sure theres a sign on the roof that says Metered Taxi and doesnt say Grab anywhere those you get the 1st km for 35 thb
