@Atazhaia Maybe someone should introduce them to an even more advanced piece of technology. For instance, imagine if you will, a small plastic square that, when pressed, pushes two pieces of metal into contact. Then imagine that removing the pressure on the plastic square caused the metal pieces to move out of contact again. Now, let's, for the sake of argument, give this a nice, cool-sounding word, like, say, 'button'.
Now, and this is where it gets ingenious, imagine you can have more than one of these so-called buttons. Then you could have a set of, say 11, and write the numbers 0-9 on 10 of them, and GO
on the 11th. Then, and this is the really clever bit, you can connect these 11 buttons to a small PCB with a small programmable IC on it, and then you can type in, say, a two-digit code then press GO
, and you get the drink you wanted. Of course, to know what code you need to enter, you'd have to have a list of drinks and codes. A menu, if you will.
Alas, I fear such advanced technology will not appear in our lifetimes...
