On several occasions when asked for details of my name, address, dob, etc… I have asked why? Employees reaction is typical “Because we have to collect this information”. I get the impression that staff think I am being rude, difficult or obnoxious.
And unless provided you cannot get the required service. I realize that staff are only doing as their jobs, so there is no point in engaging in any further discussion. But I do reserve the right to ask: Why? Take it or leave it is ultimately the decision.
Sometimes I use false information – if they don’t want to see an ID it hardly matters. In light of yet another data breach (aka Culture and Heritage), I am even more reluctant to give away my personal information.
