Apparently this is a fairly common occurrence at Starbucks. I understand the occasional contamination happening, but flat-out putting an ingredient that was requested to be replaced is horrible. People aren't always trying to be fancy with "food fads"; some people are legitimately allergic.
And it shouldn't even matter if they're trying a " food fad ". They asked you to do what you're being paid for so you shouldn't be doing shit like this on purpose like I've seen so many people do.

Weird.
