thats nasty but think about the bed, ppl piss and do all sorts of nasty things on it and they only change the sheets. When i stay at a hotel i bring my own pillows and ask for extra sheet to lay over the bed.
They had an article on this a week or two ago on TV with hidden cameras and the staff who was caught not washing the items properly were made to do a cleaners course again. They will always do it half-assed anyway.
