The website says open 24/7 but because I was feeling terrible and wanted to make sure I didn't drag my butt out of the house for nothing, I called ahead to make sure they were open. The girl who answered the phone told me no appointment was needed and I could just come on in. I arrived an hour later to find the door locked, lights off and nobody answering the phone. What the??? Really don't appreciate my time and energy being wasted when I did my due diligence.
