Why did he address me as ma’am?

So the guy who works at the hotel addressed me as ma’am, he’s Indian by the way. And I’m thinking in my mind wtf? Especially when I have a toddler. I understand I don’t look 20 anymore but I’m damn sure not a ma’am at only 37.
He was just being respectful
He low key tried to insult me/hurt my feelings
Maybe in his culture they think calling every woman ma’am is polite
