Some nice creative shots there, Gambit.
I would love to use my 50mm in the club/bar where I work, but there are many situations that arise when I'm asked to take a large group picture. Many people also think that because you've got a lens on the end of your camera it can do everything. You can only stand back so far before light fall off and space become a problem.
one of the clubs I cover 2 nights a week, has RED ceilings and RED walls... disaster for bouncing.
Try black walls and high ceilings.
