GTE - yes that makes sense - that is what I expected.
As they didn't train me, and they don't know me, I would be very surprised if they let someone loose with a plane after 20mins! I would expect no less than most manoeuvres, ie, stalls, steep turns, PFLs, basic flying skills.... before returning with some circuits with different approach flaps, maybe even a glide approach.
I have seen PPLs who are very capable, and I have seen PPLs who I thought were definitely trying to kill me on final approach... I have seen a PPL do a "left base join", by flying the left base, followed by the right base, followed by turning onto right hand downwind, before making a max rate turn at 800' before joining downwind for a right hand circuit. So I wouldn't take for granted anyone who came through the door!
