Firstly, it is not unexpected to see a thread like this. Even if "everyone knew" Julie's was underpriced and the economy was sailing, htere would be complaints of a price rise.
Second, there are several ladies who have raised their prices very recently and found business was not adversely effected.
Thirdly, I have heard of several cases recently where ladies left "lower priced" places to go to places which charged more, only to find themselves sitting around all day with few or no customers. Not feeling that they could "go backwards", several have now left the business altogether. There is always a huge attraction to go to a "higher paying place", sionce it not only offers the Bigger Better Deal of more $$$$, but also self worth ( i.e. I'm a $600 girl now....). This doen't always translate into more money at the end of the week, though, and sometimes means someone's a starving "$600 girl" rather than a wealthy "$200 girl".
Lastly, while the following doesn't say anything about any individual place ( statistics never do ), it says something about where we are headed: From the places I have spooken with lateley, if you make a graph with price on one axis and number of clients served on the other, the slope of the line has increased substantially lately ( in other words, the cheaper places are getting busier and the more expensive places are geting slower ). In fact, while most places I have spoken to recently have gotten slower, the cheapest places are getting much busier. To me, this indicates a shift of some of the same customer base, who can no longer afford what they used to, from higher priced places to lower priced places.
As an aside ( and to keep to our tradition of restaurant analogies ), everyone wants to open the place of the moment, with things like "beef cheeks" on the menu, celebrities, fancy decor, etc. At the end of the day, they drive thier 1973 Buick home, passing the two Mercedes in the driveway of the guy next door who owns a couple of MacDonalds franchises.
