Advice for B&M customers anyone?

[neoflex]

I hate the know it alls. You ask an employee about a stick and the know it all customer steps on him and proceeds to try and tell me everything he thinks he knows and than proceeds to tell me why I shouldn't smoke the stick I asked about but insists I try X, Y or Z instead because they are his favorite. These are usually the guys that live at the shop and even most of the staff can't tolerate them.
