Iffy Centre 

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.

I think I'll go down to the Iffy Centre as I'm not feeling so good today.
