Old People Shopping on Saturdays

I hate old people shopping in the supermarket on a Saturday. I know you’re old, dear, and that you need to eat, but why not go on a weekday between the hours of 9–5 while I’m at work and you’re not? When I get back from work I have an hour to get all my shopping and get home, then I get stuck behind Betty counting her pennies at the till… COME ON!
