Met him once. I was working on the water softener in a TGI Friday in London. Passed his table a few times and always let on. He then asked the waitress what I was doing going to the kitchen with all these tool boxes, I informed him I was making sure that all the burgers had the right amount of Mad cow in them. He loved the joke said he would use it one day. Bear in mind this happened around 1996-7.
He was there dining with his kids who cant of been more than 6-7 years old. So sad, R.i.p Rik.
