McDonald’s complaint: Rudeness

My grandson is 13, We was coming home from football practice, Was about 7:40pm, He was hungery so he went in alone to order a hambuger and a drink. At first he went in alone. He stood there about 5 mins and no one said a word to him, he came back to the car. So I’m his grandmother so i went in with him thinking it was cause he was a kid. So there were 4 cars in the drive thru. There was 5 people inside eating. i stood there for ten mins waiting for someone to take a small order. I could see two people just standing not doing anything. So i said hey is anyone going to take our order. The younger people working didnt say anything. But there was this older man that snapped and yelled at me that they was short handed. I was so surprised about his behavior. I said we would just leave. On the way out i told him i was going to report his actions. In that amount of time it wouldnt have taken a min to key in a order. or if they would have said we will be there in just a min. Everything would have been fine. He was so rude and yelled hateful. i will never stop there again. You need to read some of the reveiws that has been wrote down on there behavor. I was so up set on the way home it took awhile to get over it. i just couldnt believe he yelled at me like that.If there that shorthanded the manager needs to hire them some help. I have never been treated so rudely.
