Not afternoon tea in the Ritz sense but an afternoon cup of tea - sure! But I could have tea any time I liked day or night by pressing the call button.
Yes but it is for anyone under caution, not just being arrested. It is slightly different however in that while there is an absolute right to remain silent, the court is at liberty to make an adverse inference if you bring up a defence (in court) that you could have brought up at the time.
Therefore the wording of the caution is as follows:
I was wearing slip ons. I had plenty of time to make a shiv if I had any of the materials or had a clue how to do so.
Edit: I just remembered I had to leave the shoes outside the cell in any case.
Makes sense; thanks.
