Today it was sat on 'my seat' as I walked in.
In my fellwalking days, I used to eat in the Bank Tavern in Keswick. It used to get chokker with the tourist trade in summer, so the locals had a refuge from the grockles around a little table in the bay window just inside the door. One day when it was rammed, they called my dinner, and as I stood beer in one hand plate in the other, there were no seats available anywhere...except in the window bay. So I ate my dinner with half a dozen regulars sat in silence looking daggers at me.
Another trivial annoyance that isn't really trivial, seeing the little energy efficiency rating card thingummy that came with out last TV
It irks me that they made A the best rating for appliances, so that as they got better they had no choice but to add A+, A++, A+++ etc. Eventually they redefined the whole system a couple of years ago, and what did they do: the same again. Lack of foresight or what! Why don't they just have 1 as the worst, then they can add 2, 3, 4, etc. indefinitely.
It reminds me of rock climbing grades where they kept dreaming up ever more fanciful names as routes got harder, before giving up and just numbering them as they could have done from the outset.
