Stopped in to get a quick slushy. Only two cars were there. I hit the button and waited. After a few minutes no one answered so I pushed the button again. Waited a few more minutes and still nothing. After about 10 minutes of waiting and seeing a girl take food to another car I hit the button over and over until someone answered. Finally...I placed my order and paid at the screen. The slush came out quickly but it should never take over ten minutes at a fast food place when no one is there. I think I'll find a different location next time.
