At work we recently moved to a new building which has been adapted several times, some spaces have had multiple uses and multiple security level changes. The present use of rooms is different from the original design. As a result walking down the corridor requires a combination of pressing buttons, waiting for automatically opening doors or simple manual operation.
I can see new people coming down the corridor and people regularly get caught out by at least one door waiting for a manual door to open automatically or alternatively trying to manually open the automatic doors one set of which have heavy hydraulics.
Light relief when I am having my lunch.
