I think there could be. I've personally helped friends and colleagues out with Excel stuff from time to time and have been able to show them some basic tricks to save lots of time and they come away thinking I am some sort of Excel ninja guru!
But then again it baffles me that people will persist with an hour of some boring drudge re-typing or modifying something in a spreadsheet without thinking "There must be a better way, should I look for it?". But maybe these people are beyond help and not customers?
