My son, who went to culinary school, assures me that anytime a person eats out at a restaurant, they eat a little bit of the cook.
I've heard some stories on that subject... some more disgusting than others. Like the Pizza Hut employee who went to work hungover and the smell of food caused him to add some regurgitant to the vat of sauce. Apparently nobody noticed because nobody complained. Then there was the cook who felt insulted by a female patron who complained and made derogatory comments about the mayonnaise on her chicken breast fillet, so he replaced her meal and added an au naturale 'mayonnaise' of his own.
As for an appreciation of maggots, well yes, they are great cleaners, particularly with infected wounds and the like (I had them packed into my right leg after it became infected after bone graft surgery), but that's about as far as it goes. We had to move these real dirty people once (the gov't resumed the land for a new road), and believe me, it wasn't at all pleasant.
On the first day we noticed scores of maggots all over the floors all throughout the house, but persisted and got half their stuff out. On the second day (it was a mammoth job with all the junk they accumulated and wanted to keep) we were greeted by thousands upon thousands of flies. Neither my partner or I wanted to go inside the house, but the removal had already been paid for by gov't and we didn't have a lot of choice. Let's just say that we tried fumigating the place before starting work, but 6 cans of fly spray later we didn't get rid of them all and had them flying in and out of various facial/cranial orifices while we were trying to work.
YUK wasn't the word. It was absolutely the absolute worst removal I had ever done. The filth in that house was unimaginable and it should have been condemned years earlier. Fortunately for everyone within a 20km radius, the gov't bulldozed it and put a new road on top.... but I'll bet pounds to a pinch of sh!t that the brand spanking new house we moved those people into was just as filthy within a few months. They had absolutely NO sense of cleanliness or hygiene whatsoever.
YUCK maggots ewwww, I know I couldn't eat them
Actually, the chocolate coated ones are quite nice... and much healthier than a Mars Bar.
