Nooooo, you were NOT rude!! She most definitely was and I'm so sorry to hear she's made you doubt yourself!

I have such low self esteem and somebody calling me rude would upset me a hell of a lot (I still remember being told I was "blunt" 5 years ago!) so I understand it's knocked you back a bit and made you start thinking "wasI was rude??"... but no, you weren't.

I think if it had been me I would have just shrank away, just accepting that this RUDE woman was pushing her trolley into me... but I think it's really cool of you to speak up. But not in a rude way, just in a real way, sort of, making her aware that she's pushing you and asking for her to wait for you to move. You have every right to say what you did, and I admire you for it.
