You need to read AND think before posting.
The man readily acknowledged each fact that you point out, including the right of Costco (or any other private busineess) to prohibit the carrying of firearms on their property.
It's not clear to me what your complaint is about.
My complaint is that the guy encourages people to boycott COSTCO for some percieved insult and or violation they commited against him.
COSTCO does none of these thing IMHO and the guy comes off as an ass.
And no he doesn't acknowledge the fact that scaring a clerk who is only trying to do his friggin job is not funny.
He also doesn't explain how a supposedly concealed weapon made other shoppers uncomfortable (doesn't sound too concealed to me)
He also doesn't admit that they did NOT ask him to leave they asked his gun to. He pitifully attempts to make it about him when it's really about him flashing a friggin concealed weapon in a store.
What he does admit is:

Why do I get the vision of Travis Bickle standing in front of a mirror mumbling over and over again "Are you talking to me" when I read this hmmm
