Yikes, all that grease... *barf*
This topic reminds me of a school trip we did in elementary school, we were 13 or 14 years old and had to bring enough food with us in our rucksacks since the trip included an overnight stay at a cottage in the mountains.
What I remember the most from this trip (besides hating mountain-climbing with a passion) is a classmate of mine eating from a can of tuna fish during one of the breaks along the way. I can still remember the scraping of her fork as she ate the tuna (and sitting on a rock) while the others had the usual snacks like sandwiches, croissants, energy bars and such. Me, I was so tired I couldn't eat much, really.
There's the image of the oil dripping over the edge of the can that I can't shake, plus that scraping and the content look on her face...
Still not sure why I found it rather bizarre back then, I guess it had a bit of an "icky factor" and it obviously stuck to this day. Strange!
This topic just made me remember it again. Sorry if it's off-topic.
