If I were to categorize people by profession and then rank them, I have to imagine door-to-door salespeople and telemarketers would generally be the most irritating. Despite my no soliciting sign on the front door and my polite, "no thank you, I'm not interested", the sales person that rang my door bell today still attempted to hard sell me. I found this to be all together disrespectfull. Should I need a pest control company it will not be this one.
