As a test, we tried makeing a call from a booth in klong toey to see how well the payphone worked.The sound that came out from that handset was low in volume,so one had To practicelly shout to communicate.And it took a few sheets of wet tissues to wipe off the dusty grime-and hopefully disinfect the machine- before We dared put the phone next to owface,or even pick it up with our bare hands.
