Said it before...
IF you find yourself in the position of having to deal with plod.
1) Be polite.
2) Say nothing, don't explain, don't justify, silence is your right. "No Comment", "Am I free to go?", "I would like legal representation" are the only three things you should say, and silence is better than any of them.
3) Ask for a lawyer, check they are in fact a lawyer and not plod.
4) You don't have to assist, don't give your name, or any other information. Let them read it off your driving license etc other pieces of ID on your person.
5) Don't consume any food offered to you if at all possible, water is fine, but they are not there to help you, they are there to provide information to CPS who will decide if "reasonable prospect of securing a conviction", sadly it doesn't matter to them to convict the right people. A "solve" is all that counts, as in their rather grubby book with large print, the court of appeal is there to deal with that.
6) Don't get lippy, 1096 deaths in police custody since 1990, zero convictions. https://www.inquest.org.uk/deaths-in-police-custody
