My wife and I are planning on opening our first drive thru shop. We're negotiating for a location with a traffic count of approximately 40k. I'm trying to determine what we can expect for traffic through our shop. If we use the .5% to 1.5% numbers we've seen here we get some pretty good sales figures. I'm concerned, however, about our ability to actually move that many customers through our shop. We realize that during the rush hours there is going to be a maximum number of customers that we will be able to serve regardless of the amount of traffic flow. Does anyone out there have any information on how many customers we can expect to move through a double-sided drive thru shop in an hour??? Any insight would be greatly appreciated.
