It's true. The cashier at Seven Eleven (a moody ladyboy) dragged herself to the counter and smashed her hands on it. After taking the money she dropped the 4 baht one by one from a high height into my hands as if to say 'you have disease I don't want to touch you'. I litterly had to get a blood test, an xray and a urine sample for the school I work at. No diseases here.
