Monday: Either Or

Having been stuck in the office all day with no means of escape (despite trying to make a ladder out of sheets and dangling it out of the window), I had two options for a blip today.  One was the canteen at work, the other was some underground art en route to the Bakerloo line at Embankment tube station.  Suffice to say, this is not my canteen at work so I will leave you to guess what it might be.
