I knew someone who was very proud of donning a suit on the weekends and crashing his neighbourhood churches, synagogues and catering halls to get a free meal during weddings, funerals and other events.
I guess you have to be good at BS, though he did have some good stories to tell, both during the event I'm sure, as well as after. So much catered food goes to waste. Might as well get it at the source. Perhaps in my doddering years I might adopt a similar tactic as "Old dotty Aunt Meghan" and it might make for some good sport.
