Take action and do everything you can to get this message out. Write posts on Steemit about it, spam Starbucks emails, call them, and do whatever you can. Maybe they eventually get tired of it, decide to take a look into SMTs and actually decide to take action and implement it. That would be huge for Steemit!
I am sure going to make a post on steemit about this real soon. The word needs to be let out and Starbucks has to know about the potential steem wields in the crypto world.
Honestly ,having steem used by Starbucks would be a banger.
