Would you consider this rude behavior?

I was invited to a new friend’s house and I had suggested I would bring take out Indian food. I got a bit lost so I phoned that I would be late. When I came in the open door, she called out that she would be with me soon. She was chatting on the phone and continued to talk for another 10 -15 minutes while I stood around. She told me it was her brother on the phone when she got off but offered no apology. Meanwhile, the food was getting cold. What would you have felt and done?
