Went to Vnukovo in the middle of January a couple of years ago.
We had to wait hours in the handlers portacabin to get our visas issued. The floor was soaking wet, it was -153,000 degrees celsius outside (or at least it felt like it!), it was getting dark, we were sitting on the filthy camp bed etc...
There was no indication of when we would get our visa's as the handler just kept telling us it would be about 5 mins.
Handler "We didn't know you were coming"
Capt. produced a fax from them showing confirmation of our handling request
Handler "Different shift worker"
Capt. "When will get our passports back"
Handler "Before the passport office shuts"
Capt. "When does it shut?"
Handler "It's shut now"
Capt. "Oh. I'm sorry I don't understand"
Handler "They need to open the office to shut it. They will do your visa when it opens and then they will shut it"
Cabin attendant didn't help when she asked if she could have "seasonal vegetables" for the return flight.
Keep 'em coming
