Is there one in a rapide? Or are the passengers 2nd class citizens who either deserve to hold their own drink, or just not drink in your lovely motor….?
I think you might find a shoe storage compartment, incorporating a numbered ticket dispenser though. Passengers not allowed to wear outdoor shoes in a Rapide. Beautuful carpets.
Two in the back one up front. As passengers will generally have two free hands , just tell them to hold it and stop the moaning. Then floor it everything they try to take a drink.
