I'm not sure about your area, but the small local stores in my neck of the woods generally have a judge that is already on staff or is the store owner, and thus has already been background checked. Do people actually hire judges for events that are not large tournaments held by either conventions or large-scale organizers who can afford to do this?
Most stores do not just have a certified judge on their regular staff. Most stores just have a person who plays in a lot of their tournaments and knows the rules pretty well, and sometimes they are certified. If they start comping that person's entry fee to encourage them to help out more, and that person is certified, they are now obligated to do a background check on that person and they
definitely will not.
I mean, you have to have a judge to run a PPTQ.
Most -big- stores I have been to have a judge on the staff - generally someone that became a judge because they run the events.
