selling water

I went to IKEA today and they had some very little cafe or a restaurant. The options for food were - hot dog (very, very,very bad one) with an option of mayonnaise-mustard souse only, very-very awful piece of pizza and a doughnut (can't say anything - I haven't try it). As for drinks they had production of Pepsi Co. and they had free refills. The problem with drinks was - they all were mixed with water! Can you imagine Pepsi or Mirinda with water? It was so gross! Basically, they've been selling halp-product & half-water for the price of product. I hope at least they've been using filtered water... Although I doubt that.
I wonder if Pepsi company is aware about damage that IKEA is doing to their brand?
