That's always struck me as kind of strange. I'm a long-time customer of our bank, and every once in a while I get another query asking if I accept to continue receiving this, and I say, “The fact that we're dealing with you at least a dozen times a year makes this kind of silly.” A six-month or a year's timeout on a business transaction or an inquiry is the sort of thing.... They should be keeping the permission alive indefinitely. It doesn't need to be renewed.
