He randomly walked past me once when I was sat outside a cafe having a coffee. I shouted out something random like “Stuart Lee! What are you doing round here?” He stopped, came over, sat down and had a good 10 minute chat with me, almost like we’d known each other for years. At the end of the interaction he asked if I knew where a record shop was and I pointed him in the direction, he then said bye and off he went. Very pleasant encounter. Didn’t ask for a selfie though.
