Flower,
Just wondering - if bad RT makes no difference to a clearance but you keep a closer eye on the fluffers, do the competent sounding ones get left more to their own devices when receiving a service?
Reason I was wondering was because I accidentally

managed what I felt was some fairly good radio work on a sunny Saturday around Brize recently and suspected I was left alone so they could concentrate on the foreign sounding guy that kept saying say again, etc. This is not a complaint! I like being left to my own devices and wasn't expecting much of a service at all on such a day anyway. Just wondering if unofficially this is how it works.
