How many massages do you do in a day?

Before I started my mobile massage and spa business I used to do 8 massages a day. I was employed at a very swanky spa in Beverly Hills and it was a great place except when I was expected to crank out so many massages. The spa manager clearly had no idea how exhausting my work was nor did she consider scheduling me a break to eat.  I used to keep a stash of almonds and bananas under my table so I could at least keep my energy up. Bananas were great because peeling them wouldn't make any noise so my client wouldn't hear.  How do you survive a workload like this if you are not scheduled a break?
