a visit to Heathrow would help.
All day we see overhead/deadside joins. Plugging the poor guy in bandboxed GMC would definitely help his PPL.

go to a small GA airfield (a FISO or A/G unit) and then a bigger airport that has to integrate VFR traffic. Much more beneficial.
If that doesn't work - go to an RAF tower and drink lots of tea.
