Two Pumps of Caramel?

My special lady likes the caramel macchiato at Starbucks. As her partner in crime, I've been indulging in a couple of these myself recently - smooth velvety caramel, melted in a rich blend of frothy milk and fresh roasted coffee. Delicious.

And suspicious. This last weekend, we dropped in on the neighborhood Starbucks and the barrista manboy behind the counter took our orders, two tall (meaning the smallest size?) caramel macchiati and with a lurid wink at my special lady, said 'two pumps of caramel right?'

What? I asked the special lady. He knows your coffee order like that? What else does he know, in the Biblical sense? Is my wife making a cuckold of me with the local Starbucks barrista?
