I mostly grind and brew our family's coffee here at home, but I've never seen a Starchucks, Peet's, or Dutch Bros barista or clerk not bust their tails. Maybe it's trained-and-phony customer service shtick (I doubt it, though), or maybe they are being their more or less natural selves, but their work ethic that I've seen is just fine.
Snowflakes are out there, I assume, but I haven't seen any here in Silicon Valley. And speaking of workers busting their tails for customers, In-n-Out and CfA people do it, too!
