An Iffy Centre is a a walk-in primary care, nurse led facility, for minor ailments and bumps and bruises.

Prompted by the description by Andy Buck of Rotherham Primary Care Trust, as a place where people can see a nurse if they are feeling "a bit iffy."
He used the word five times when defending the spending of £12,000,000 on this new facility when interviewed by Gerry Robinson for BBC TV.

The practice of TV programme producers using one of the same small group of supporting cast actors in different programmes, because they choose "characters" rather than actors, thus there's no time wasted "getting themselves into the part" required.

These actors will play similar characters to that which they played in another recent drama, some as in period dramas, even wearing similar costumes to those they wore before.
It seems that sometimes, as soon as these people "exit stage right" in one drama, round they come again "entering stage left" in something else.

There are too many pathology based crime dramas on TV these days.

A "justgetme" is something, (plural "justgetmes") which a wife asks her husband to purchase on his way home from work or wherever.
These are usually small purchases like a pint of milk or a loaf of bread, but sometimes can be a few items amounting to as much as £10.
Of course, the purchaser will not see any of the cash for these purchases, whether they are for them both, or personal requisites for his other half, who I imagine assumes the funds for which come from "an imaginary source."
