Dairy Queen Grill & Chill

I want to start this by saying I've never left a bad review on any restaurant before. Not once. But I feel as though I really need to when I comes to this place. I'm unsure if I've just been very unlucky or if this is a consistent thing, but everytime I've been to this Dairy Queen something has been wrong. I've had multiple times where my items have been forgotten after I paid for them. I've been given the wrong thing as well. I've even corrected them only to be given something that isn't what I asked for at all. I saw I was being handed the wrong size drink, so I politely corrected them, only to be handed the right size of the wrong drink. As well as asking if they had given me the correct amount of sauce or things, and being told that that yes, everything is in the bag, and when I check those things are STILL missing. And this has happened multiple times. It's ridiculous. I feel like if you go here you might as well just tell them to surprise you and deal with whatever you get. Either way, I don't think I'll be eating here anymore and if you do I wish you luck.
