For shopping lists, Mrs L and I use the AnyList app, which is fab.
My grumble is with local authority (East Staffs BC) who have upped the parking charge at Uttoxeter Leisure Centre from £1 to £1.40 for the express purpose of getting on my tits. No-one in their right mind would pay for parking in Uttoxeter because there's loads of free parking elsewhere, and the Leisure Centre refunds users anyway. But you still have to put £1.40 in the machine, and because of Covid, they're only refunding onto cards at the moment...
