I haven't done this for soldiers but I have done it for college kids and old folks sitting all alone. For me the coolest part was not letting them know who had done it.. The first time I tried this I told the waitress I'd leave her $20.00 on my $6.00 tab if she would just tell them their breakfast had been paid for. It was really cool to watch them try to figure out who they thought had been the one to pay their bill.
I get just random people from time to time. Usually it's at breakfast, I get them when they least expect it
