A shop in St Louis used to have a two tiered price for fixing flat tires.
They had one price for fixing the flat while you waited. And another, higher price for if you left it to be repaired. Their logic had to do with the cost of paperwork, dealing with the customer twice, having to store and retrieve the bike twice, and the physical cost of space to store repair bikes.
