I had a variety of cheese related traumas, of which two still scar my memory.
One is of going into a diner on Broadway that advertised "Jacket potatoes with broccoli and cheese" in the window. The girl behind the counter placed some wet, rubbery broccoli on top of a spud and then went over to a tap. She operated said faucet and out oozed... Bile-yellow emulsion? Pus? That is certainly what it looked like. It didn't actually taste of anything.
The other (and worse) encounter was with an allegedly "Gourment cheddar with port" I bought in a supermarket. I swear the manufacturers go round to all the chiropodists' practices at the end of the day, pick up all the bags marked "Highly toxic medical gacky foot waste -- do not open", and stick the contents in a big press overnight, heated to optimum festering temperature. Then they cut it into rectangles and sell it to suckers in supermarkets.
This was an experience I had truly never had in my life before: cheese I couldn't eat. Needless to say, the seppoes in the office thought it was delicious.
