I thought that too. If I wasn't so scared of wearing white... (I'm cursed when it comes to light coloured shirts.)
Saaaame!

Ha! That's the first thing I noticed. If someone were to only want that (or anything other than an amiibo, really), would they have to wait in line!?
Waiting on the amiibo line if you only want to buy a game or anything that is not amiibo-related wouldn't be fair. Maybe you just tell the guard that you come to buy other things and do so freely. But then the checkout... to the amiibo line then!
