This immediately reminded me of Viktor Belenko [1] who flew his MiG-25 to Japan and defected. He wrote (I think, in his autobiography, it could have been an interview) of the amazement that dawned upon him when he entered a Western supermarket for the first time.
edit: found it.
"Once I bought a can which said "dinner." I cooked it with potatoes, onions, and garlic-it was delicious. Next morning my friends ask me, "Viktor, did you buy a cat?" It was a can of chicken-based cat food. But it was delicious! It was better than canned food for people in Russia today. And I did test it. Last year I brought four people from Russia for commercial project, and I set them up. I bought nibble sized human food. I installed a pâté, and it was cat food. I put it on crackers. And they did consume it, and they liked it. So the taste has not changed." [2]
