Quoting from this interview with Viktor Belenko,
who in 1976 piloted his MiG-25 fighter to Japan:

Belenko: First of all American super-market, my first visit was under
CIA
supervision, and I thought it was set-up; I did not believe super-market
was real one. I thought well I was unusual guest; they probably kicked
everyone out. It's such a nice, big place with incredible amount of
produce, and no long lines! You're accustomed to long lines in Russia.
But
later, when I discovered super-market was real one, I had real fun
exploring new products. I would buy, everyday, a new thing and try to
figure out its function. In Russia at that time (and even today) it's
hard to
find canned food, good one. But everyday I would buy new cans with
different food. 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. By the way,
for
those who are not familiar with American cat food. It's very safe; it's
delicious, and sometimes it's better than human food, because of the
Humane Society.
