Selling low margin doughuts with high overhead (pretty girls) sounds like a business flop...
How many people really care about pretty girls on the way to work, when doughnut shops see the bulk of their business? It might be cool for a few visits, then it wont matter... and it might turn off a large chunk of their potential customers (women).
... and if they charge more for the doughnuts, to compensate for the high labor, people will eventually go to the cheaper place they go to now.
