My Fayetteville location is at a mall, but it is not "the mall", it has a theater, but is not the main mall. We have a rear exit and have it on our lease to be open 24/7. We have to close the mall gate when the mall closes and if we trigger the mall alarms, I will get fined. So far this has not been an issue.
My Columbus, GA location is in a mall, the main mall for the city. We are open just mall hours. If I had a location that had it's own entrance (not just a back door) the mall would let me have extended hours, like the restaurants do. We have been written up there for opening too early. The mall opens its doors at 8 am for mall walkers and we would have customers on Fridays and Saturdays waiting for us to open, so we started opening up early. The mall will not let us open before 10 am. We are normally 100% full by noon on Saturdays and 1 pm on Sundays (open at noon). Our lease will be up in 2013, I am not sure what we will do, we have some options (including putting in an outside entrance), but they all seem to have a pretty big price tag. They are also willing to do extended hours, but not 24/7, so I am not sure, I really like the 24/7 model. No one has to worry if we are open or not. The retail sales at this location help with the increased rent.
