This has nothing to do with party politics, it is everything to do with my expectations of how a first minister should behave on the world of social media.
I'd expect something a little less flippant and a little bit more courteous. As I said, you cannot post such cocky remarks when you're the FM and then expect tugging of forelocks in return. By all means complain but do so in the proper manner.
another way of looking at it, is this how our first minister prefers to address the people he is representing? after all, it stands to reason that the employee who responded is Welsh and subject to Carwyn the Caring's great empire. I'd like my leaders to show a bit more deference to when addressing the people they purport to serve.
