Tauschen

I am about to go to Ikea alone to exchange a table. See, when I got the table, I didn't know it was a triangle and not a square. I thought I was being tricky and saving money. Nope. You can't really keep a mouse cage on a tiny triangle table. I hope the one I need isn't sold out. It was on sale.

Where do you go in Ikea to exchange? What is their exchange policy? Is exchange "umtauschen" or "austauchen"? We will see. Maybe I'll just slur? I'm sure this is going to result in a story.
