You have to count it into the till, make change, balance the till, count and recount your deposit, and then haul it to the bank to deposit and pick up your change order, or pay an armored car service to do it for you. And hope nobody robs you in the meantime, or slips you a bogus $50.

You are thinking of that bastard unit the pound-mass, defined as the mass that produces one pound force at normal Earth gravity. The true mass unit for the US customary system is the slug which weighs in at 32.2 pounds at normal Earth gravity. Just as a kilogram weighs 9.81 Newtons in Earth gravity. No tweaking required.
And don't forget the metric system's own bastard unit: the kilogram-force. Which, I might add, is far more commonly used than pound-mass, unless all of the metric world's cheap bathroom scales are really sophisticated mass-balances in disguise. And whereas pound-mass is always specifically stated, kilogram-force seems only weakly attached to the force.
