For the emerging chains - the 1-10 units in a regional area, chances are that they will stay with vendor that was there from the beginning - the supplier who let their bills ride when times were tough, who brought them their signiture item and the like. With the emerging chains - there is still a hands on owner-visionary who owes a couple of favors to their wholesalers. They are as tough, if not more than the chains.
The key to these emerging accounts is to get in when they are still at the 1-3 unit stage. That is when you get their loyalty.
For the health department guys - yes, you can set up an appointment, but don't think you will get much out of them. My health department leads came from years of seeing these guys around. I would be in a place when the health inspector showed up. After seeing them a couple of dozen times, we began to talk. I would drop hints about places that needed an off season visit, and he would tell me who needed different cleaning chemicals.
One of my accounts - a school district built a new school. The architect neglected to obtain the necessary kitchen permits, which nobody figured out until I asked for it for our records (company couldn't ship to places without one). At that point, when they realized what had happened, I sat down with the health inspector, convinced him that it was an honest oversight and the district administrator did not know. The health inspector agreed to allow the permits, on the agreement that I would do the food deliveries and oversee the cleaning and setup for their first visit so that they would pass the inspection.
I got the information about the new accounts because they recognized that I was a good rep - and that I would not do anything that would endanger the public health. But it took a long time to get to that point where they would trust me. It is not something you will get with a drive by appointment. They have a responsibility to the taxpayers and have to stay neutral between vendors. They are not going to "spill the beans" unless they know you and respect you.
