'If I say "I am getting the next train to Nottingham" I mean the next train not the one after the next one.
Likewise next summer means the next one not the one after the next. (How can that even make sense?)
If it's a Monday and I say let's all meet at the Pub next Saturday, I would not expect to be sitting there on my own with everyone else turning up a week later.
If I am next in the queue at the doctors I expect to see him/her next, not to have someone else jump in front of me saying... "next, means after me".
Englanders are renowned for their queuing etiquette but if you start messing with what "Next" means then there will be riots on the streets.'
I agree with the next train and next in the queue but the pub example always gets English speaking people arguing. If it is Monday and you say next Saturday, I guarantee you at least one of your friends will ask 'do you mean this Saturday or next Saturday?' I have heard this argument come up many, many times, correctly or incorrectly I might add. I am not claiming this to be 'correct' english but from my 40 years experience in the UK this is how some British people use 'next' when referencing time (** I should state although I am born and bread in Britain, I do not claim to be an expert on the peculiarities of the English language (of which there are many)).

According to previous forum posts it is at this point customary to slag off Nottingham or people from there but I will leave that to the 'next' poster, they have enough problems already tee hee hee... sorry couldn't resist
