I’m old enough to remember when the prices went above £1 a litre, all the garages having to get their signs updated so they could have four digits on the price. Some of them using wheelie bin stickers or handwritten "1"s as a stop gap.
Wonder what they’ll do this time around, the ones that didn’t think far enough ahead to have a full seven-segment display fitted?
I remembered when this happened in Australia. they just ended up painting a section the pole the same colour as the rest of the number.
