In fact, I called back for one of the interviews. They said they were Starbucks. I said where. Their response was "Here at Starbucks"
"Which one?'
They are calling from Starbucks. How can you not know what Starbucks is? Are you living in a cave or something?
You'd be lucky if they actually told you which Starbucks. Don't remember the actual brand/model/component, but I have gotten questions like:
“The OpenGL on my ThinkPad doesn't work!”
“Which ThinkPad is that?” (would ask what ‘doesn't work’ means later)
“ThinkPad. It's a laptop. You claim to be an expert, but don't know what a ThinkPad is?”
That happened personally and off-work, since I don't work with clients (putting me with clients would be a crime against humanity), but it also happens to co-workers who do. From time to time it will even happen with something that's actually cryptic and we haven't heard of. They come asking after being berated from clients for not knowing something, and it turns out nobody in the whole company has heard about it either.
We just love to assume people know what we are talking about, don't we? I've had something like this happen:
“Let's meet at [X], at the monument.”
“You're ridiculous, how can you not know the monument at [X].”
“There are three.” (turned out the person was talking about neither of the three)
“The monument at [X], there's one, don't be ridiculous”
I go there, go to a five-foot tall monument right next to one of the eight entrances to [X], and the person naturally doesn't show up. I call, deliberately pretending to be mad that they aren't “at the monument”, so that they don't do it first. Turns out they were waiting somewhere inside [X] (a big place with restricted/paid access), near some tiny figure the size of a human hand that was... the monument.
