I frequent Starbucks. No sign of the hashtag lecture.
My sense is that, unless the barista is an idealistic leftist college student out to settle some horrible injustice in the world, very few baristas will participate in this "conversation." Especially at rush hour, they are trying to get customers through the line as quickly as possible, which won't happen if they're trying to engage every customer on the issue of race. Also, most of them won't be willing to initiate a conversation on a potentially controversial topic even if it *is* during a slow period. They don't want to upset the customers.
I don't know what the CEO was thinking when he came up with this idea... maybe it's just an early April Fools... maybe he needs to go on that undercover CEO show to be reminded of the reality of working in a customer service position.
I was in the 1st Ave. Starbucks in Seattle on Friday for my usual coffee and newspaper. The cups had a Race Together sticker pasted on, but no lecture from any of the baristas that I was able to hear. This particular store is just a couple blocks north of SBUX world headquarters.
