Ha, I can relate to that. Met a potential in the mid-2000s who lived down the road running a travel agency which was falling over due to bugs in its web app. He knew nothing about technology other than that his app needed to parse "an XML" to work properly. "Can you get the XMLs working?". As soon as he showed me a couple of files I realised it was a Classic ASP site written in VBScript running on some overpriced Windows host so I offered to rewrite it in PHP. No chance - in his mind "the XMLs" were glued to the original code.
