Coin Exchange of Treasure Valley

I recently went into the Boise Coin Exchange to ask a few questions on some coins that I had, the owner was extremely rude and completely dismissed me because I didn't know what I had. Also, you have to be buzzed in to enter the store, I know he deals with money but come on, as a customer I should be able to come and leave as I choose. Don't give this place the time of day.
