Probably a bit off topic:
Iīve been on a summer contract in E.Europe and appearently a memo had been issued to cabin crew that they where also not allowed to leave the hotel after midnight.
Seen a local Capt. talking to his CC pretty unpolite pointing his fingers on that memo. Since I couldnīt read and speak that particular language I took his and my crew out that night and we had a great time !!!
Guess thereīre still some companies who think that they own you once you signed a contract...
