If it's any comfort to you guys, I live in a unitary authority, far fro m the Scottish border, which apart from the edge which is bordered by water, is surrounded by the County whose leader recently made the government's day by demanding to be put into a tier higher than local circumstances dictated.
So, with one friend, different postcode but same Borough, I can enjoy a meal / coffee and cake / alcoholic beverage indoors, 0nly not at one of our favourite meeting places, because that's over the boundary. However, we can't do any of those things indoors, anywhere, if we want to do them with the third member of our little gang, because she lives over the boundary (but actually in the same main postcode and, indeed, postally in the same town as I do) and so the Tier 2 rules apply both in her area and to her personally, as a resident thereof.
(Inevitably, the even more easily confused than the rest of us, who live on our Tier 1 side of the line, are saying that the confusion should be dealt with by moving us into Tier 2, too
).
Next week, DS2 and I are going on a campus tour at the University of Kent. I am now wondering whether we will be stopped somewhere in iour neighbouring bit of the County Council area (and will they count 'going on a campus tour' as a genuine educational reason for our journey?), or if not, refused entry to the other, Tier 1, unitary authority, where the QEII Bridge starts, because once we get there, we will be trying to enter from a Tier 2 area...
