Some of the ARCOs here in AZ are fairly nice and I can stop in there to use the facilities. I do buy some gas there but usually don't top it off. I prefer either Shell, Chevron or Costco. Had an experience with a Chevron that I topped it off at and went in to use the bathroom when they told me that they close them down in the evenings. I understand that the reason they do this is to prevent homeless people from using it to take a "birdbath" in the sink and/or shoot up and possibly die in there. I was told that I could go to a QT down the road. At the end of it all I never buy gas at the chain anymore as this experience soured me on them.
