Am I wrong? Did I overreact?

👀

So, just popped into my local drug store (I am in the UK) to grab a couple of tests. Approached the middle aged woman at the counter, she had previously just served a young mother and was being really sweet with the woman's son.

I got to the counter, said "Just those please" and she looked up at me and said "So hows all of this going for you then?", I just looked at her in complete disbelief and told her (in a rather stern manor) to mind her own business and to not be so nosey.

She then pointed to a sign below her that states something along the lines of "Abuse towards our staff will not be tolerated".

I was thinking of reporting her. Is it worth it? Would I be wrong? I just feel so hurt that a complete stranger would ask me something SO personal without knowing ANY background information and then have the audacity to threaten to kick me out once I called her out on it.

Thanks all.
