I've never been to prison

When you go to prison, do the police give you half an hour to sort out your life before you are locked up? For example, can you:

1. Top up your ISA?
2. Do the washing up (imagine how mouldy your cups would be after 5 years in the slammer!)?
3. Lock your front door?

There must be many other things as well that I haven't even thought of.

I know prison is supposed to be a punishment, but is part of that punishment the continual worry that your kitchen might be overrun with new species of growth?
