Difficulty With Doors

Needing help with a controller for the garage door we went to the saleroom to sort the problem.
Their street door was open but all was rather quiet and surprisingly empty apart from a yard broom and a couple of soft seats, but there was a light shining in an office area near the back. Curious, we wandered around calling for a member of staff... or workman... or a cleaner... anybody?? to tell us what had happened to the company - but there was not a soul in the place. I took this photo of the mural on an internal wall, if only to prove we did not dream the entire episode.
