Problem is that most retail places are scared to death of bad reviews online and so everyone gets their ass kissed regardless of their situation.
There needs to be room to tell someone their behavior has now crossed a line and you need to leave and do not come back.
Trust me when I say that the folks at the LGS have had their fill, and bad reviews or whatever, they're at the point of not caring. Most of them will tell belligerent customers where the door is and to not let it hit them in a$$ on the way out.
