I have gone to this store for 5 years , since the purchase of my home. Today I was told by the female clerk you can't read. Do to the fact I asked her name. She was the worst person to have handle your cash. She has attached a I am better then you look and attitude. I had a my own glass. And filled it with water, even my own ice from the house. Payed for a fountain drink so I used a Casey's cup and put water in my own, instead of just walking out with both I let her know that I put water in it that's, when she said I charged you for a medium and not a large you should have spoke to me before you feeled a Casey's glass with soda. I said yes ma'am, I just didn't want you to think I was walking out with both glasses of soda. Then she printed the receipt and stared at it and said what you paid $20 for gas I said, no ma'am. I paid $15 for gas and a dollar 40 plus tax for a soda. Well then she just looked at me and said you should have asked me first and I said yes ma'am, okay would you prefer me to pour it out and you refund my money I'll take the gas she said no. and as I went to walk away I said what is your name is? ma'am, just like that and she said I'm not going to tell you. I said you're not going to tell me your name, so I walked back to the counter and she put her finger over her name tag and said my name is Casey's. That's when I said okay I won't come back, she said good don't come back. Well my kids, say that not going back to your store doesn't teach her how to have customer service, so I guess, I'll go back and get gas just won't touch anything else in the store. Also, going to go speak with the manager of the store tomorrow this was a very uncalled for, and very rude,. I'm a security guard. I'm the person that drives around at 3:00 a.m. getting gas. And I would like to also say, I'm a resident next to your store, so I'm going to be here a lot longer than your clerk. I have seen so many people go in and out you place. I know how to be nice to persons. And I can say that as a clerk, and, not just a security guard I'm a clerk at Patricia's on Reno and council. I know the city pretty well. I would have been fired, I hope she has some kind of something. To learn ,so she can't speak to people in this way. It is at the store on Britton and Northwest expressway across the street from the McDonald's. The time of purchase was 12:23 p.m. older women clerk, long brown hair , flat ironed, brown eyes, dark black in skin color, weighs about probably 170. And was working a shift with two one other male employee, second male employee was walking into shift from the neighborhood I live in. Ask him what the lady's name was, and he said, ma'am I don't want to get into it. I haven't even clocked in yet. After I feel the customer complaint online I called the customer service number but unfortunately Sunday no one's there to talk with. Pretty disappointed in people right at this moment. User's recommendation: Get gas from pump and not bother the clerks here.
