The average ATCO in a quiet Tower is always glad to get a bit of extra trade ...looking out at an empty airfield isn't much fun.
When the Strubby Varsities weren't night flying, all we would have was a few Canberras taking the Staff N/Spec N students on a grand tour of the UK, in the hopes of getting them lost, returning some many tedious hours later [from our POV, of course]. So one used to ring Patrington [then the Fighter Command Diversion Cell] and assorted other airfields offering them "6,100 ft, full lighting, QGH/GCA/ILS and an empty circuit".
I think I overcooked that one night, and had to call "Enough!" as we were getting a bit hectic! Oh, and got a billow-king from DSATCO for letting a Comet do rollers without checking the LCN first*
* I assume the Captain didn't check either .. it was quite a few numbers short. Runway inspected, no visible damage.
