Having to slip the doc and the anaethetist a red envelope and hoping it's the enough that they'll take proper care of you is not a good system to live under.
Lol, that's exactly life in Eastern Europe/ex-USSR. There's socialized medicine, but if you want better service, you have to bring a gift (whisky, chocolate, money, the latter is always desirable). Not just hand cash over, that's disrespectful nowadays.
