You can probably just buy the coins online lmao
A lot of bars will give you free drinks if you give them your sobriety coin from AA.
Is that the engineers fault? Or is that the people who are supposed to check for usability after the engineer is done designing the functional aspects? Because it’s not usually an engineer’s job to do this…
Basic product testing is the foundation of manufacturing, an error like this doesn’t get all the way through production and it still be just the engineers fault.
AA sourced sobriety coins cost a LOT trust me. You dont ever want to have to find out. Not that they charge you for the coins (they do not), but whatever landed you in there likely cost you more than some online coins would, is my point.
