The reason for me is that my wife and I have extremely busy lives. For me this was a run around purchase. enough time went into sorting it.
That's why we have to cover all the possibilities. when, were & how quick they can do this. That's all it is for me. I need minimum disruptions.
you are right its not a big thing for many, but for some of us trying even to get a spare hour is impossible these days.
I sympathise but sometimes time has to be made, 4 hours is not a lot to ask and as it appears it's not an urgent recall everyone, even the really busy ones should be able to plan ahead.
