I work in glass/construction service and go to peoples homes and businesses daily and have been for about 5 years. I have never got a complaint as far as my appearence or manners go. Then again I am a very good looking and clean person use manners and almost always wear my uniform. lol... You just have to remember people are letting a person they have never met or know nothing about into their home, so people are going to be judgemental of your appearance because thats all they really have to go by.
