Is it a red flag if your dentist asks you if you don’t want to be numb during a cavity filling?

I’ve been going to the same dentists office for the past four years, the owner of the office is also the dentist. He recently started expanding his business and is hiring more staff including a new dentist. This new dentist asked me if I wanted to skip the shot and numbing for a cavity filling. I’ve had a few fillings in my life from various dentists, including the original dentist at this office and I have never been asked if I wanted to skip the numbing. Kind of took me by surprise a little bit, but I went with “ absolutely not”. Is this normal or a red flag for a dentist to completely forgo the numbing?
