It is always a disappointment to not to get a soda when you have added a dollar bill into the machine and the machine just decides at the last moment that probably you are the not deserving one to have that soda. The machine, the very machine that pops that soda on to someone else a long with another soda to someone else who just paid for that one damn bottle.
This guy however teaches you to get past that phase of hatred towards vending machines and try and make the best out of these mindless machines. All you need to find is a machine that has this rolling belt kind of thing and also the calculator like buttons to punch in the numbers again when needed. So he just inserted the bill into the machine and for Coke Cherry he punched in the code and as he narrates how th belt goes to the departure point, then down and then up again you just need to press the button again in order to pop that second bottle on to the rolling belt as it reaches that point and there you will be having two bottles at the price of one with no hassle at all.
