is this door broken ?
mu guess is that a 'semi-automatic' door is probably half as automatic as an 'automatic' door. but i could be wrong.
it looks like this wasn't always the case though. what actually happens is you grab the door and need to give it a good push to open it. as soon as it starts to open it suddenly becomes automatic and drags you in to the building society.
go to abbey national in wokingham to experience this for yourself.
This is REALLY a challenge on our ability of thinking! I am glad that I don't stand there - I would freeze to ice instead of moving... but maybe this is the aim (to give some cooling, when you just consider the time of the year).
