I was in a go-round coming into a Swiss airport early last year. As a highly-strung and greenish SLF, I was lucky to be sitting next to a commercial pilot. He looked up, snorted something about "Turks parked on the runway again" and went back to his book.
No panic apparent from CC or pax and all went smoothly next time round. No explanation was offered, but think I'd have been worried if the pointy-enders had stopped what they were doing to have a chat.
