To make it worse, there are the ones who have purses with lots of pockets. There's a pocket for the banknotes, another for the credit cards, another for the discount cards, another for the coins, another for the special offer vouchers, and another for the receipts.
I once got stuck behind a woman with a purse like that and all the pockets were zipped, on three sides no less. The whole queue waited and watched in amazement as the purse spun around like a catherine wheel.
The performance was repeated, once to get all paraphernalia out and then again to put it all away. Each zip had to be opened twice and closed twice.
On the same subject, I am dismayed by people who don't know how to use a credit or bank card. They have to be told which way around to put it and need three tries. Then they have to be told what a PIN is and need to check a piece of paper somewhere in the wallet, and have to try each PIN they've written down until they find the appropriate one for the card they're using.
This latter syndrome applies to middle-aged men who, presumably, go to the shops only when the missus can't. The shopping typically comprises one bottle of whisky, one sliced loaf and one can of baked beans (or a bread roll and one can of Spam if they can't cook).
