3 down to 2 stars. After getting a few thousand coins via FB It's a clear rip off. It takes thousands of coins to upgrade staff every 2 levels but levels only give 100.It costs $20 for 7,000 coins. If you purchased enough coins you'd be in the hole over $50 per location...that's the price of a console game. I know they have to make $$ but other app games DO NOT do that especially with such simple and repetitive play.
