This morning, I missed my train by couple of minutes and had half hour to burn before the next one. Popped into Mcdonalds and there was a guy sitting one table in from the door, who had obviously slept out that night and was looking cold. I walked past, and then double back and lightly shook him on the shoulder (he was dozing a little) and asked "Hey pal, did you want a hot drink?" he was very thankful, but said that someone else was grabbing him a drink, so I wished him well.
