I was talking with an executive of a large grocery store chain last night and the conversation turned to the low gas prices. This person said it was not a good thing. One reason, which surprised me, was that with a bit more money to spend because fuel was so low, many people are going out to eat more and grocery store revenues are down. Consumers are shopping for fewer groceries and stores have the data to show this.
In which case eating places are probably of the belief low gas costs are a good thing. It's never an either or when it comes to fuel.
