A schnoz by any other name smells the same
When charged an exorbitant price for a service or price it is not unusual to proclaim " I paid through the nose". Of course the larger the proboscis, the higher the price. If the price is so high as to be painful while exiting the schnoz it is fitting to tell the merchant " up your nose with a rubber hose" which I'm sure would not be welcomed. Beware however, that if this retort results in an altercation, you would not have a leg to stand on in a court of law. All in all, paying through the nose may be messy but it is cheaper than paying an arm and a leg.
