I used to work at Starbucks (almost a decade ago now), but at the time, the motto was “just say yes” to any customer requests. We also had free drink cards that you could give out to deesclate any issue. So I would say any time you’re even the slightest bit unhappy, bring it up, and you should at least have your problem solved, if not compensated for a free drink next time.

We also had customer satisfaction surveys that would print on reciepts, where filling one out would get the customer a free drink. We always kept them for customers that were happier to try and rig the odds in our favour of a higher rating, but also if a customer asked for one, I would give it if I had it. You could always ask the cashier if they have any of those as well.

Again, not sure how much either of those things have changed in the past 10 years, and I’m not sure how regional it was (this was in Canada at a corporately run store), but maybe worth a try.

Also I love these types of threads – great topic to post.
