I guess it is basic tech these days

My wife suggested we get Chinese food from a place on my way home from work.
So, I called in the order as I left work.
I thought it was strange they didn’t ask for my name with the order, but figured I’d just ask for what I ordered.
When I got there I found they had my order ready by my name as they matched my cellphone number on my phone in to my previous orders.
I guess that is good.
But, a bit strange.
