Many good going clubs are living on the presence of some live staff, mostly a host, better going clubs also a live dj from time to time and a security officer.
In many clubs I can always here the slogan "Please don't forget to tip your host - we're working hard..." - this is nonsense. The work of a host is no hard work at all. It's mostly greeting people, something you can do with some good macros at east. Perhaps just also looking if the people behave, and if not, ejecting or banning them as last measure and that's all.
This is a kind of job, that's quite easy to do and which I also appreciate, but it's no hard work at all. I almost cannot stand this saying anymore.
