You know how sometimes you glance at something written, and sort of read it quickly without paying it too much attention, and you can sometimes get it a little bit wrong? And then it sort of sticks in your brain until one day you look at it afresh and realise that you've had it wrong all this time? (And to be perfectly honest it's not a bad little mini-lesson in the way we tend to label things.)
It turns out that the cafe near the office, the one I have been visiting about 3 times a week for the past three weeks, isn't the name I thought it was. Cafe Voka is not in fact the jauntily named Cafe Vodka.
I still think I like my original version better.
