One of the drivers of customer brand insistence is accessibility. I recently encountered a local bookstore with these hours. It is a new store and I love books so I wanted to explore it. Despite driving by the store a few days each week, I have not yet gone by at a time when it was open. I have now given up on the store. Unless the brand offers a highly demanded item or items not available anywhere else, inconvenient store hours will completely take it out of the consideration set. People do not have a high tolerance for inaccessibility, especial in the era of Amazon.com and a myriad of other 24/7 online stores that can ship overnight.
Clearly, this is an extreme example of ridiculous hours of operation, but I have encountered many other places with similarly strange hours. If you don't uniquely offer the next big thing, don't handicap your business with limited or strange hours. And even if you are uniquely offering the next big thing, you would do much better to offer as much accessibility and convenience as possible.
I suspect the bookstore I am citing will be out of business within six months, if not sooner.
