     Theodore, the mamger of the Paradise Hotel, told a middle-aged couple that they would have to leave the

hotel after just one night. The couple, visiting from Texas, had booked a room for eight nights. 

     "They wanted a sterile (消毒了的) environment, "Theodore said. "They should have rented a room in a

hospital, maybe an operating room. This hotel is clean, but it isn't that clean."

     Theodore said that, on the very first day, the couple bmught all the sheets, pillowcases and bedspreads

down to the rmin hall and just dropped them next to the front desk. They stood there next to this pile of

bedding while other guests looked, pointed, and mumured. The hotel got three cancellations within the hour

from people who witnessed this strange event.

     When Theodore asked the couple what the problem was, they said that their bedding was filthy and they

wanted it replaced. The couple could not identify any specific "filth" on the bedding. The wife just said, "we're

paying good money to stay here. How dare you doubt us? We know the filth is there. That's all the proof you

need." Theodore called room service, and the bedding was replaced immediately.

     Early the next evening, however, the couple marched to the front desk again and demanded seven cans of

sterilizer. "We need a can for each night. We have to spray the phone, the TV, all the door handles, the toilet

handle,the shower stall, the faucet, the sink, and any hotel staff entering our room."

     Worried, Theodore politely suggested that a hotel more suitable for them was just around the corner. He

then called ahead to reserve a "very clean" room, and gave them free transportation in the hotel Rolls-Royce.

A1so, he told the couple that they wouldn't be charged for the second day.

     The couple were surprlsed but they really liked the idea of free room for a night and that expensive car

service.
