I just saw an interesting thing returning empty bottles to a store, there was a lady before me who had returned alot of bottles and i only had one, but when i put my 1 bottle into the machine it flashed the ladies sum of 37€ before it quickly switched to 0,15€ and let me print out my receipt of 0.15€, so i just was wondering if it was possible for a hacker to find an exploit and print out the receipt of the previous person who used the machine, not that i would ever be skilled enough to do that but i would like to know if it was exploitable, im just interested. (I dont know anything about coding)
