Some time ago you commented that every single time Jick makes a coinmaster he does it in a new way. It seems that he's still struggling to break your ability to adapt.
Perhaps he envisioned this one as a multi-use, not a store, but then decided to put in a list of options to make it easy for the player. Terribly disorganized. I guess he wasn't modeling this on the example of the AWOL commendations after all. Too bad, I thought that was a very successful experiment.
