"...having to prod the keypad after all you nose-picking buttscratchers have had a crack at it."
You reminded me of a study some uni students did in my town a few years ago. They took samples from ATM keypads around the city and did some forensic testing. Among the substances they found on the keypads were traces of:
Saliva and nasal mucus (there's your nosepickers);
Human, cat, dog, bird and rodent urine and faeces (there's your buttscratchers);
Coffee, fruit juice and soft drinks;
Assorted sauces, meat and vegetable food products in various states of decay;
Human skin (natch), blood and internal organ tissue(!?);
About the same quantity and species of bacteria per square cm as found on an average public toilet seat;
And I've saved the best for last: They found traces of human, BULL and PIG SEMEN on the keypads. Somewhere in my city, there are pig and cow fuckers going around using our ATMs (probably farmers having done artificial insemination, but I can't speak for their hygiene!) As to the human semen, the less said the better...
Mine's the one with the disposable surgical gloves in the pocket.
