In 90+ degree weather? Gee, just sit it out in the sun for a few minutes. THIS, FRiends, is what entitlement thinking does to people.
If the meals weren't heated, just place them on a black roof for a while. When I lived in NJ, the driveways would get so hot in the sun that you could burn your feet on them. Anyone who would turn down food is not really hungry.
That "entitlement thinking" cuts across a lot of spectrums: to wit -
I worked at a hurricane shelter several years back. We were serving hot dogs and sandwiches. One person [obviously middle class] going through the line threw it back at one of our servers, saying, hot dogs? is that all you got?
