It can't be so expensive that all of the inspectors' combined bribes become too expensive for the least able institution to afford. You don't want the bribes to be such a burden that someone complains, either. When you're inspecting possibly multiple businesses in a day, 5 days a week, all those "cheap" bribes add up to a nice tax-free bonus paycheck on top of what the government is paying you to do the job.
