A strange experience at the Building Society yesterday. I called in to hand in a routine form as a customer. As I was there, I thought I might as well ask for change of a tenner (useful at this time of year for collections etc). To my surprise this seemingly innocent request was refused. On enquiring the reason, I was told "the regulator won't allow us to give change". I then suggested that had I brought in my passbook, deposited the tenner, I could have immediately withdrawn ?10 in the fiver and five ?1 I wanted. The somewhat sheepish reply was "Yes". Clearly some Building Societies and regulators do not inhabit a planet where common sense exists. Life does get more complicated.
