My parents bought a business a while back (about 8 years I think). It's a steep learning curve to start with and I would encourage either you or your mum to do a crash accounting course if you haven't already. Also, talk with a lawyer before signing anything - if it is as part of an existing business partnership with the gym even more so because there'll be all kinds of existing agreements etc.
If you do make a go of it please please please don't sell chocolates - that's one thing that has always infuriated me about gym cafes!
35kg lost. (November 2005 - October 2006)

Back to the drawing board - Let's do this thing!
