Like many residents of this city an occasional stop at the “Starbucks Public Restroom Service” happens, but as I was waiting on line I found a set of Bodum 3oz Insulated Shot glasses with ounce increment markings for sale ($10.95).

As far as I can tell these do not exist on the internet and I think they are an older version of the Bodum Assam 2oz shot glass.  The glass I’d been searching for was from a specialty coffee distributor called Rattleware who make a 3oz mini shot pitcher, but these insulated Bodums (with a silicone pressure regulation seal at the bottom, no less) appear perfect for pulling up to 3oz shots and are certainly nicer to drink espresso out of.

Bodum Assam 2oz: the version I bought has parallel straight glass walls and two 1oz interval markings, allowing up to 3oz total volume
