Guy i know was riding home from his work and got knocked off his pushbike by a car at a junction. The older couple got out and checked he was ok, said "we only live up the road, come in and clean yourself up and make sure you're alright". While the wife made him a cup of tea and washed the dirt off his jacket, he was chatting to the husband, talking about how he was into records, and the guy went "oh, i've got some records from years ago if you want to have a look". He ended up doing a deal and going back and buying the lot. Sold 3 of the records for £1,500 the next week and paid his rent for the next year on the rest, and still kept a load for himself. It does happen, just not to ME! lol
