I'd ban them from coming out at rush hour altogether. Retired people have all day every day to do whatever it is they do, there is no need to have them dawdling about between 0730 - 0900 and 1630 - 1830.
I never used to be able to get the bus to work as it would just sail past the stop because it was full of pensioners.
They get up at about 0500 so by 0800 they have done all of the pottering about around the house they can manage so it's time to get the bus down to Woolworths where they will spend an hour examining every item in the store.
Then they purchase a new salt cellar or something equally unnecessary (as long as it costs less than ten bob) before doddering off somewhere else, the bank or the post office usually, where they will complain in a loud voice about having to wait in a long queue due to 'all the foreigners'.
