Speedway review: customer service

Me and a friend went into this Speedway to pay for gas and had to use the restroom so we walked over to the bathrooms...when we got close we noticed two stacks of plastic bins in front the doorway but not in front of the bathroom doors. We assumed they were unloading stuff or moving these bins and hadn't placed them in the right place yet so we moved one stack slightly aside so we could get to the bathroom door. We went in and one of us proceeded to use the restroom when we heard an extremely loud banging, scaring us half the death and if I must say we thought the SWAT team was possibly outside of the door. The lady then proceeds to scream outside the door, being very rude "Get out. Now!" This was screamed multiple times. We immediately opened up the door and two workers were standing outside the door glaring in at us. The black woman who wore a black speedway shirt and a woman wearing a gray shirt, looked as either could have been a manager. They continued to be rude and tell us the bathrooms are closed and that is why the bins were there. We felt EXTREMELY uncomfortable for two people trying to use the restroom and these women made no effort to be nice or friendly but instead gave us dirty looks and walked away. We were not aware the bathrooms were closed and think a sign hung up the door could possibly help out people instead of a lazy attempt to block the doorway. The black woman acted extremely unprofessional and rude that I was honesty blown away by the whole situation.
