Is it weird if the delivery guy wants to take a photo of your ID or driver's licence?

Was talking to my mum earlier and was telling me that when her groceries were delivered, she was asked to provide id so he could take a photo because she bought alcohol

And he needed to show it to his boss

And she said to him that she always buys alcohol and no one has ever asked for a photo of id before,
And she also said that she's like 100 years old lol

But yeah, he eventually left and didn't take a photo of the ID

But my mum was telling me that she felt uncomfortable because of all the scams that have been happening lately
