Why is it parking machines do not have change dispensers? Say it is 60p for an hours parking and you only have pound coins; no smaller denomination coin? If 1 hours parking was 50p then you could purchase 2 hours parking; not 1 hour leaving 40p in the machine - The remaining (in this case: 40p) amount does not even remain on the display so someone else can add 20p for the 60p hours parking; the remaining amount is extra profit for the capitalist parking authorities
