Not sure I understand how it works (maybe I am just daft) and I even watched the video. So you load the card then drinks are only $1? Are they specific drinks each bar makes for this reason? In the video he orders two "treasures" but then says he pays them like he pays anyone else- so are the drinks $1 or are we donating a $1 and then they cost the same as any other drink?
I would love to do this for my upcoming trip but don't want to look like an idiot when I have no idea how to use it.
