Unnecessarily complex change machine
John shows the above example of unnecessary complexity that he found in a San Francisco Muni station. To get $1.50 in change, you put one dollar into one machine to get a dollar coin, then another dollar in the other machine to get quarters.
Then, I assume, there is a third machine that takes both types of coins.
Ick.
I think this is a by-product of the fact the US totally doesn’t like or understand dollar coins. They’ve failed so many times. Yeah, this example is funny in how complex it is–but still, there’s a basis in the whole dollar coin thing.
I’m pretty sure you could just use the machine on the right only.
