Is it flirting if a guy goes out of his way to open the door for you?

I was in a white neighborhood and when I reached the cafe door, this guy who was about to head out the door, deliberately stepped back into the cafe, swung open the door for me with effort. I told him that he didn't have to do that for me and he could just come on out. But he insisted. I blushed and said "thank you so much". I couldnt make eye contact cuz I was shy. He was a handsome man.

I don't know if this is a flirting move or if its just him being super nice. I notice its usually men who have done this for me in the past rather than women
