In the past, I've had Farmer's Market and special events permits in Iowa. This year I've upgraded to a Mobile Food Service Unit permit. I have never had a problem with the inspectors, but then again I study the regulations make sure we follow the rules. I think a lot of it depends on the inspector and your attitude toward them. Most of the inspectors are decent people with a really crappy job. Sometimes you just have to let the seemingly petty criticisms roll off your back during their visits. You can find the rules here: http://dia.iowa.gov/food/
. They are good about answering specifc questions or you can PM me and I can try to help.
