Westwide Gas Station

On may 3rd at 11am I just left the job site on base and stopped at the gas station to fill up for my trip to Va. Beach. I was at pump 18. Went inside to pay cash for my gas. Put my drink on the counter and tried to prepay my gas. The lady asked for a military id. Now I'm confused I have been coming here since this job started and never had a problem but this time I couldn't get gas because I'm not military!? I've always been told no alcohol or tobacco bc it's not taxed. I'm fine with that. And to take the cake she was snippy. I did not get her name but she was the only lady working the front regester at that time. This is just ridiculous.
