I remember back in the 80s I bought an Ocean game from a flea market. When I got home it didn't work. So out of pure cheek I phoned Ocean and explained it to them and to my surprise they said to come down to the office and they'd replace it!
I can still see everyone scurrying around while I stood there in awe watching them all at work. Was my dream job and couldn't believe I was seeing it live.
It made an impression on me that they treated their customers so well that I still remember it. I wonder how many companies would do that now. I can't remember the game, I think it was something to do with Robin Hood.
