GF,
A friend of mine had such a conversation with a Swedish airman.
He also hosted a WPC Classic crew, Romanian or some such.
Come 4pm Friday he looked at his watch and suggested happy hour. The visitors looked distinctly uncomfortable. When he explained what was to happen they repaired to the Brize bar. "Was this something new now the wall had come down?" No, we do this every Friday.
"You do? We always stood to on Friday afternoons. We were told that this was when you would attack."
