we cleaned a pig sty, (actually do quite a lot) and iwas prespraying a landing and put an extra squirt on some hard chocolate in a corner, i then heard vommiting noises coming from my helper, he'd run the enviro dri over the "chocolate" only to find it was 5h1t with a crusty shell and when he scrubbed it the whiff was absolutely disgusting, i laughed my t1ts off while he was gagging, anyway, cracked on, job done.
