UGH!!! I hate rude people!!!

Today I went to Babies R Us... had to get the kids diapers. Well Kenley started to get fussy so I took her out of her carseat and she started to root and cry harder when she couldn't latch on to me. I knew the store had a "mother's room" so I had Caleb watch Aiden and I took Kenley to feed her. When I got back there, 2 women were in there changing a babies diaper. I didnt say anything thinking they were either about to feed the baby or had just finished. I walked around for a few minutes and went back to the room. One of the ladies was sitting on a couch bottle feeding the baby in the room. I politely asked if she minded if I used the room to breastfeed my daughter... who at this point was SPAZING OUT!!! The woman looked at me and said it was gross to breastfeed and she wasnt getting up or sharing the room with me.... I'd have to wait. There is a bench right outside the room that she could have sat on to BOTTLE feed the baby... she didnt need a room with a door to have privacy. I WAS LIVID, but didn't want to even humor her with a response. I'm still not 100% comfortable breastfeeding in public so I found Caleb and told him I was going to the car to feed Kenley. THE NERVE OF THAT LADY!!! I'm still angry about it.
