... evidence of British worker tea breaks!!
I recall in Canada we would tend to see a pile of binned styrofoam coffee cups. Here, it's much more civilised mugs - with real milk, and a tray no less!
And the guys have even aligned the mugs in an aesthetically pleasing pattern based on colour and available equipment.
No sign of any Hob Nobs though - must be a council job.
That spare mug of tea looks a little watery.
Lots of people are taking mugs to work, to ease up on disposable cups, nice to see!
