I was closing down a bank account, all the while being watched by a stranger leaning at close quarters against the counter next to me. Some of the attention that I should have been paying to the woman behind the wicket who was assisting me was diverted by the stranger's proximity, to such a degree that, fearful I would not be able to accomplish the bank transaction satisfactorily, I informed the man that my banking affairs were private matters and that he should back off and give me some room.This he did with a slightly embarrassed laugh.
