It would be better if she just had a barback that could do ice, open beers and do the general clean up. She could just stay in the well and make drinks. I don't think having someone help out for an hour a day would be a big deal.
It would also help if people knew what they were ordering before they get up to the bar. I am sure the question "what's good?" drives her justs as nuts as it does the next in line.
