I'm not being mean when I say this but I think that your night was probably a lot more pleasant than it would have been for other people because you are girls :) I wasn't in a bar affiliated with any particular team, but I have been in them in the past and simply wearing a jersey for the opposing team would get at least drinks dumped on a man that was wearing a kit for the "wrong" team. Men turn into apes towards each other when sports are involved.
Later on in the same day as the Super Bowl game here in Vietnam I went for a run and was still wearing the Chief's shirt. Two people shouted something at me as I was running and i could see by the look on their faces that they were not saying anything nice. I couldn't hear them though because I was wearing headphones.
