Equipment should always be checked prior to use. Even if a piece of equipment seems to be functioning perfectly, back-up equipment is needed for critical operational functions. Oftentimes, the equipment will work great in an empty stadium but when people arrive there might be an equipment mishap. This is a common scenario with wireless microphones, headsets, and other communications equipment that is sensitive to interference. Give an example of event that you have attended where they had a mishap with the equipment. Did they immediately fix the issue? Did the issue have an effect on your fan experience?
