We’re currently in NYC and still chuckle to ourselves when we recall trying to get coffee on our first visit here years ago.
Back then, it was pretty hard to find decent espresso coffee but we’d been tipped off that Dean and DeLuca was reasonably reliable. We happened to pass one and popped in. The conversion went something like this:
SYD+1: “Can I get a long black”
Me:

Server (young woman): “Ya wanna whaaat?”
At this point I was hoping the earth would open up and swallow me. But it didn’t, so I started crab walking toward the door while SYD+1 was blissfully unaware of the faux pas and was providing guidance on how to make a “long black” (espresso with extra water…)…
A lady in line says, “Are you from Seattle? That’s how they order coffee - lots of instructions”!
Anyway, the educational bit is to ask for an Americano…
