Brill exmouth market
If they could have a little more prep space and have two people making the food, plus have a bit of a sense of urgency this place would have a roaring trade. I've never heard a complaint about the food, in fact quite the opposite, but I know three people other than myself who just can't be fussed to go there any more.
And we all buy lunch every day. They're really missing a trick. Good selection of coffees and bagels, with plenty of sweet treats to follow if you feel like it. Really like the range of vinyl for sale as well.
Six years after that, as CD sales declined, coffee and bagels were added. The business model works because the rent is already being paid on floor area, while CDs are racked up the wall attracting no extra overheads. And the two products are symbiotic. You listen to the cool music while you drink your coffee and then take the CD home.
Of course no business is that simple: I well know, having owned delicatessens, that thousands of pounds worth of small packages on your shelves can suddenly look a very small pile for your outlay.
And you need to be canny enough about your stock so that it sells regularly, and regular customers see new items in the racks. Would you measure the metre between the furthest two points of the scratch? Then an even worse problem was discovered: The rod was shrinking!
No, something had to be done and that something involved changing the definition of the metre fundamentally. Neon signs have characteristic colours due to the electron transitions in the ionised gases.
It is here that cadmium comes in to the story. Rather than use a physical length that we could all measure, the people whose job it is to define our base units decided that the definition of the metre would be with reference to the wavelength of the red light of Cadmium. I do not know why they did not want to use the red of neon lights but even with cadmium it quickly became apparent that there was a problem.
So, rather than cadmium, in they settled on the orange line of Krypton as the definition of the metre. One metre was then defined as That was the definition for over twenty years before the definition of the metre was updated again in Nonetheless this definition does allow people to perform experiments that need very precise and very accurate measurements of lengths.
