As an investor you seem only pro NAB with your money on the line. Any business looks at all sides.
Basic issue of concern: don't know what yerba mate is. I like Bob Marley, etc. Let's try it. Ooh good. I like yerba mate. What is it? Oh, cool, neat tea. Wait... they add coffee caffeine in this? That's not genuine. I got played.
Option 1: let's go to Disneyland, I'm a stupid American = big money sales
Option 2: hhhmm, think I'll drink the real deal. Marley family sold out. I'll move on. Or, the company which bought their name is selling them out. I'll definitely move on.
