My car was overheating, so I pulled into Valero near Austin Community College, North Ridge, Austin, TX. I decided to get gas since I had to check out my radiator anyway.
They only had one clerk behind the counter who was on the phone for at least 5 minutes. I tried to get his attention, but he shushed me and told me he was busy on the phone.
He then refused to sell me gas once he was off of the phone. I know it seems harmless, but he was very rude as are most of their clerks at Valero.
