I'm generally willing to give someone a pass for repeatedly emphasizing that their statements/projects/opinions are not in any way affiliated with their employer. I don't often make statements tangentially related to my work, but when I do I try to be as clear as possible that I am just a dude and not a spokesman, and beg people not to blow my statements out of proportion and get me fired.<p>On the other hand, this man appears to be a marketer, so I assume that he has plenty of opportunities to try out his marketing ideas at work, and doesn't do them as a side project. I think the biggest question I have isn't "did he do this on his own time, or during his 9-to-5?", but "were 'real' people putting money on the card, or did the Starbucks marketing department just refill it when necessary?" As long as it was real people putting the money in and taking the money out, it's still an interesting social experiment, even if it was crafted as a marketing campaign.
