when a person says "excuse me" because they are trying to get around you the customary thing to do is for them to wait for you to move rather than bulldoze their way thru. that was rude on her part. as for your response we weren't there so we can't judge your tone but the fact that you are so concerned in hindsight makes me think you probably weren't rude but just caught a bit off-guard. don't sweat it!
