Weird Lady Took A Photo of Me

Hi Redditors of Surrey. I was standing in front of Save on Foods KG hub, waiting for my wife while she grab a few items, head down on my phone, scrolling through social media and minding my own business when I noticed a lady who just came out of the store was staring at me.

I ignored her and proceeded to look down on my phone, then noticed that she was still standing near me. When I looked at her, she was taking a photo of me. I ask what is that for and she responded “it’s for illegally spying and stalking”. I asked again what did I do, but she walked away towards George Junction.

Didn’t see this lady before so I absolutely have no idea what’s that about.

Question: is there anything I should proactively do in case this lady does something with my photo?

Thanks.
