I can print off a quick receipt from Testmeter.co.uk or wherever. All you need is Word and a printer.
When I had the shops, this nobhead was in there all the time going on about the scams he had. One was because there were loads of empty houses on a nearby estate, he got catalogue items sent to these addresses, then on the delivery day, took a deckchair and sat in the front garden. 'Oh, is that for me mate? Yea, of course I'll sign for it'.....
So who's to say this fella isn't doing the same. 'Yep, this is my house, it's all above board. I'm just doing a spot of gardening.'
That's what I would do, if I was a grifter.
