Another thing I see with dealing with people,is a lot of people a unhappy and miserable,and they try to bring it to other people,I deal with the public as well,and I can usually tel the ones that are,they just try to be as difficult as they can be,and try to make you feel like crap,just like they do,and when its a woman acting like that,I tell my wife that night she just more secure in our marriage...when its a guy doing it ,I just smile a lot and be real polite.that really pizzes em off,because as soon as you get mad,you have made them happy...............
