>>21453579>>21453688I remember changing the price in soda machines as a kid, treat the array of buttons as numbers, use 4-2-3-1 to gain access to the config menu, 2 and 3 were back/forward, etc. Soda was cheap back then but in baseball stadiums they ramped the price up from 25 cents to 50 cents a can. My Dad would give me 2 quarters for a soda, i would change the price to 10 cents a can, buy 5 sodas then change the price before returning and my Dad would always find it funny
