We have a few,
Its similar to pub cleaning. Only I would say much dirtier! Especially the toilets!
Use to be a pain especially when you could smoke at the night club.
Lots of broken glass generally, shifts vary on times that i can be done and I wouldnt say it pays as great as a standard office.
Theres nothing special about cleaning them, its just a bit dirtier. You might need to clean the bar, and bar stools, depends if it chrome or brass so you might need durglit or brasso to bring back the shine.
So a little more work than usual.
Sometimes be prepared to find the odd needle, pill, condom. Oh You probably will need a plunger for the toilets each time.
So now you know the pit fulls you can charge a little more.
Hope it helps
