There are also "barber" shops where the about 20 seats are lined up side by side.
When these are occupied (long queues outside) the lights dim. Whistle blows.
Someone comes and unzip the customer. And start jerking them off. There
are intermittent whistle blows - presumably to provide and idea of the passing
time. Then, there is one long blow of the whistle (not unlike the end whistle of an
EPL game). If the customer no cum by then, he gets wiped and zipped up anyway.
Next!
