Nay lad, you are dead wrong, Sheffield is South Yorkshire, see.

Manchester lies between Cheshire and Lancashire.

They do actually make some yorkshire tea which is good to take to China like, a hard water brand. Us simple yorkshire folk like a piping hot cup of tea like. I don't know about Barnstaple mind, but it does sound like a place in yorkshire does it not? Now then my dear lad, it's time for you to carve out, make your mark, I must get you grafting.....no nice words of get it, got it, here. [edited]

When I first started work at the funeral parlour, we used to take cold tea(mixed with milk and sugar) in lemonade bottles and drink it cold-try googling it. Actually in those days that small opening at the top of the bottle which you'd swig out of was a wise restriction because whereas there's no flies on Devon folk haha, there used to be many on and around the Dear Departed- if you have a cups you might find yourself drinking the odd fly, in the summer that is; no AC and filters in them days......but must have been the same in the sewage works, surely? Bloody glad like yourself to be a teacher now, am I right or am I right?
