I once had a friend who was a service technician for a macerator company, he used to come to the Hospital where I worked to carry out service work on Poo Macerators,In general conversation about what a load of shit these machines were, he told me about a time when he had to service a machine at this very LAB you were in, it a legendary machine called the "DOG BASHER", basically you could put a Alsatian sized dog into it ,switch on , and dog would get MACERATED and flushed down the drainage system.I wonder if its still there?
