Many years ago ( pre-internet) I advertised for sale in the Sunday Times a BMW 325i for, if I remember correctly, about £16k.
I received a call from an Italian man who said that, if the car was as described, he would buy it for his wife and would I bring it the restaurant he owned just off Bond Street in London.
I agreed – it was about an hour away- and duly showed up with the car. He looked at the car for about 30 secs, didn’t want a test drive, and agreed he would buy it.
We went into his restaurant and through to a back room where he reached under the table we were sitting at and gave me a plastic carrier bag and said ‘man to man there is £16k in here’. It was a unsorted mess of £5s, £10s and £20s.
I really didn’t know what to do, counting it would take ages and there was clearly an element of trust and respect expected from him.
I took the cash, uncounted, and headed off to the nearest branch of my bank, fully expecting to be mugged at any minute. Made it to the bank where a helpful cashier arranged for it to be counted in my presence.
There was exactly £16k in the bag.
Bank transfer / bank draft is a much lower stress solution.
