Sonic Drive-In

If I could I would give the Sonic a zero . I came thru an hour before close. I ordered a number one with only cheese sandwich and number one meal all the way the guy asked me if I wanted them both cheese only as I had already explained one all the way and one plain and I said No Sir I want one with plain cheese only and the other one all the way. He asked what would you like to drink with that. I said a coke with light ice said I would also like a cookies and cream milkshake. He proceeds to tell me that there aren't any cookies for the cookies and cream milkshake and they are out of them. I asked what type of coffee they had if they had any frozen ones. The guy goes this isn't Chick-fil-A in a rude snarky manner, So instead I ask for an iced coffee. I get to the window after I paid I got my coke with light ice(not light at all on ice), then he gave me my iced coffee that wasn't even full!!! He told me it wasn't even full and that the reason was because it was the end of the night(cant make more with a hour left? *I've had too before in this industry *)well you still had an hour left so why can't you make more is a logical question, especially not knowing how many more people will come through in that hour. So I just ask for a refund. I didn't want a half full drink that I'm paying full price for that's mainly ice because he lacked enough liquid. So I asked for my refund the guy asked if I would rather have another drink as you know I already have a Coca-Cola with my #1meal and they didn't have the milkshake I want and now you don't have enough coffee to fill the cup up over ice so No, I didn't want another soda.I just wanted my money back so I said cert no I do not want another drink I would just like to have a refund I don't want a non full drink that I'm paying full price for it may I please have my money back. And he proceeds to tell me that I don't need to be rude. No matter what customer service you're in or what position you're in you never call a guest rude that is the worst customer service and it absolutely appalled me coming out of what I assumed was a manager. I've been in the service industry for 13 years and never in my life would I say to a guest to their face that they are rude horrible customer service!!! I will never return to this location I will drive from North Kernersville all the way to Winston or Greensboro if I want Sonic from here on out.
