you all dun be fooled! that's the power of GPS. there was once i picked up 4 passengers to the airport from toa payoh. one of the passenger left his iphone in my cab, within 10 minutes, i got a call from comfort asking me where is the iphone. apparently, the iphone was found under the front seat. a reminder their gps can track you on the road. this was what i discovered after being told by comfort.
