Faffers-about drive me crazy! I do know a few and a couple of them are old friends who have faffed since childhood so I don't think it is necessarily age-related. (How do we stay friends, I wonder? I guess it's because we're all very tolerant folk!)
We've all encountered them: they shamble through the supermarket till, fussily stowing their items into an assortment of bags then spend several minutes rummaging in pockets and handbags for their wallet. Just as they've found it and you breathe a sigh of relief, they produce a sheaf of vouchers and coupons to be sorted through before they can pay up and go. They do it on the bus, too - stand in line at the stop for 10 minutes gazing into space until the bus arrives then board and start looking for their pass/fare/return ticket in a dozen pockets and/or bags.
My maternal grandmother was a Grade A faffer and yes, she did also obsess about strange things such as the bins, meal times, TV schedules, the neighbours and other peoples' weight....
