Stopped at this Circle K at 10:30 at night. Pumped gas and went in to use the restroom. Waited outside the door for a few minutes before going to the clerk and asking if I needed a key. She said the restroom was closed for the night. I asked why it was closed and she could not give me a real answer. I asked even for customers? And she said yes. I then suggested they put up a sign so people didn't have to wait thinking that the restroom was occupied. This is one of the bigger newer Circle K's and I was shocked that they would not allow customers to use the bathroom. I will be stopping at QT instead of Circle K in the future. Wish I could have given the gas back and gone to be a customer at QT to use the restroom.
