I'm not interested in this question per se, however I am interested in vending machine design. It is only recently that some vending machines are able to take my money AND dispense my purchase (soda pop) fairly near waist level (3-4ft from the ground). However, the change dispenser of this machine is still less that 12" from the ground meaning serious bending over or kneeling to obtain the change. Why cannot change be dispensed at the same height as money in and product out - especially if there is a separate dispenser for it?
