Hmmm. Let’s see: Paddy probably pays his cashiers about £8 an hour. He has somewhere in the region of 250 shops in the UK. Managers/assistant managers/senior cashiers are left on their own every evening from 18:00-22:00.
So that £3m which the company will happily shout from the rooftops to promote itself would cover having an extra member of staff in all of their shops every day of the year.
