I've recently relocated to TX and was just denied access to the local post office with my service dog. They do have signs up that state 'guide dogs only'. Since this is a federal building and I haven't had my SD for very long I'm wondering if they really are allowed to get away with that and what I can do, if anything? I have severe PTSD and cannot leave my house without her. Before her I couldn't go anywhere alone. I find myself a bit dismayed at the thought of not being allowed to go get stamps or pick up packages sent by family....any ideas? I tried giving the postmaster the ADA handout, but she insisted it didn't apply to the post office...
