Luckily for me, I left the Kingdom before smart-phones appeared on the scene - and even ordinary cell-phones were very rarely seen - but I can well imagine how things are these days, Neil.
Something else to be fiddling about with whilst forging ahead in the Chevrolets and Buicks, no doubt!
And, when it comes to the work-place, just who is going to (dare to) enforce the "rules", I wonder?
Unless those breaking the rules are expats or *TCN's, of course!
* Is that terminology still in use?
