It certainly depends on your area and whatever works for you. If moving around works, go for it. For me, my sales went higher and higher the longer I was at my location. People look forward to me being there. And I can’t believe how often some people eat hot dogs. When I started researching for this business and reading everything I could get my hands on, one recurring theme was to get established. Be consistent. If someone walks a few blocks to buy lunch from you and you’re not there half the time, you may lose em. On the other hand, there’s a woman here in RI that owns a catering truck. She’s not like most that go to a thousand stops a day with sub par food. She serves great food and has a few stops she makes. Mostly having to do with trucking. Construction sites, a half mile from the landfill, big factory with lots of truck traffic. She found a niche and it works well for her. It’s good that you don’t mind trying new things. You’ll find your niche and be off and running.
PS…oh yeah, I wanted to mention, when you DO find a great spot, the next new vendor will see you doing good and set up across the street. What will you do?
