I was in the IHOP in Oshkosh today and over heard a partial conversation about weapons. I asked the manager about it and she said we don't what guns here. Ok why aren't you posted? It might hurt our business if we do that she says. She also said the would ask anyone they see to leave. I told her I would not be back, she should post the place, and that I would be sure to put her place IHOP OshKosh on the net as anti-gun. It appears IHOP Corp policy is gun friendly though.
Never recommend a place to post. If you are asked to leave, then do so, and then complain to corporate on how you were treated.
