Hmm ... you're right of course. I once managed a restaurant that suddenly sold several of its locations, including the one I worked at. Now I had a very booming breakfast crowd and most nights had a very steady dinner service, and my unit was making a profit. Once it sold, the new company only put out completely different menus, with different meals that had a much higher price point. My waitresses had to wear their old uniforms (that still had the old restaurant name), the sign outside wasn't changed for nearly two months and as a result the restaurant was dead just inside of two weeks.

Different situation, but I think your results would be the same.
