That was weird

So I had a weird thing happen last night at Taco Bell. Not in a bad way, but I'm left wondering what happened. So I go there and order the Luxe Cravings box on my app for the points. I get to the window and they tell me to go around to the front to wait. I do that and the lady hands me my drink and tells me they don't have the cinnamon twists and that they will be getting more on Monday and ask if I want chips with cheese. I tell her I'd rather have the fiesta potatoes. Less than 2 minutes pass before she hands me my food. I go home without looking inside. Once I get home I open the bag and guess what was inside. Cinnamon twists. I'm not sure why that exchange happened. So that's it. I was told they didn't have something and yet I still wound up getting it anyway. Any ideas on why this happened?
