Some will remember the early days of Aldi in the UK, when the individual product items didn't even have price stickers on - the till girls were just expected to (and did) remember the price of every item in the shop.And even knowing prices without barcodes.
One of the pubs I attend in Ireland has no means for accepting a card payment, the other does, but it can be quite entertaining watching 'people from the future' being dealt with on the odd occasion that it happens. The product range in those establishments is a bit narrower and more stable than is common in UK pubs - none of this "fifteen different guest ales, changing every week" thing, so it's much easier for staff to use their on-board systems to calculate price totals.
