I work in a pub (British style) on the weekends in Tokyo and I been told by
my boss that if I we don't increase our present Sunday's takings I will be
out of a job cos he will have to cut the staff numbers down.
Its a large pub with a PA , big screen , lounge and saloon area so we do
have space for something but just trying to rack my brains thinkiing what.

Can you help me with some good ideas?

Obviously this is going to open myself to some silly replies but it's all
constructive as far as I'm concerned.
Brainstorm

So far:

Live jam sessions
Tattoo night
comedy night: stand-up or just showing stuff on the big screen through the
computer

Hope you can help me.
