I saw this till in a bar in Berlin. How great is it! More and more bars in London have a crazy technical 'logging in to the till' system for their staff do use for serving. It slows things down considerably and generally means staff don't do any mental arithmetic which again, slows things down.

What's the better option? Find staff you can trust. I mean really, if you run a bar do you really want 'good' records?
