Why is it always the cleaners?
Many years ago I worked in a clean room where we had to enter an airlock, suit up, walk onto sticky mats to remove any dirt, then wear overshoes.
Normally, we'd all have gone home at 5:30, but there was a war on so we were on overtime. At 6 the cleaners came in and the airlock doors were propped open at both ends and then went about their business in their pinnies with Mr Sheen, yellow dusters, mop and bucket!
