Complete non issue...arrive a specified point, call on specified frequency and then comply with clearance.
Exactly!
I must have transitted Willy somewhere between 90 and 100 times and have NEVER been knocked back for clearance in either direction, VFR or IFR, save once when northbound VFR and sent out over Glouster at 10,000 due MIL traffic somewhere in the SW corner. No big deal can't really remember it, just complied and got on with it. It was a nice day and I enjoyed the flying.
