Disrespectful arrogant Francis at Matrix warehouse Springfield

My son frequently visits the store matrix warehouse Springfield for his gaming equipment. We have purchased all of his gaming equipment from Quentin who was most helpful and patient, thus the reason for our return to the store. Unfortunately, today, was a very different and disappointing experience. My son had arranged with Quentin to bring his PC to the store to do some rework. Francis the manager or co owner of the store was quiet rude and disrespectful. He was edgy and patient and spoke quiet abruptly to us and the employees. I wanted to address the issue at the store and I did not want to get into an argument with an arrogant disrespectful person.
