oooooh basically you have to approach the customers first, THEN use the coffee machine. man i have got to give more clear instructions on how to play the game...
Viewing post in I like my coffee dead jam comments
something that was a bit confusing was that you couldn't see the customer until you got closer to them, so the first thing i tried interacting with was the coffee machine
also, on my second run, the very first time that i approached a customer (without having prepared a coffee first) the ghost told me that this wasn't the drink it wanted... but it also didn't tell me which one it wanted before hand. this didn't happen w/ the 2nd customer
