I used to see him (and occasionally his wife) eating breakfast at "greasy spoon" restaurant called Hilda's in San Anselmo (Marin County, CA).
Hilda's sadly closed for good in the past year or so.
My son used to wait on him at a restaurant in Chicago when he came by to visit his now wife. My son, being a professional actor, had to use his best skills to treat him as just another customer
Obligatory random appearance of George.
I accidently bumped into him at the Borders Bookstore in San Rafael back in the late 90's. I was looking at the new hardbound SciFi books and he was looking at the Star Wars books on the top shelf. I just said "excuse me" and he said "no problem" and we returned to our tasks.
