Is using the F word when talking to a female that big of a deal in Mumbai?

So, I’m Indian but don’t live in India anymore and haven’t for the last 10 years. I’m currently at the Mumbai airport and sitting in the parking lot, waiting for my brother. This lady comes to the car next to me and opens her door and hits my side view mirror repeatedly while opening her door. When I try to honk at her and get a reaction, she basically waves her hands at me in the “chal nikal” manner. I get out of my car, walk up to hers and say what the fuck do you think you’re doing? And suddenly, the whole argument goes from her dinging my mirror to how did I use the F word and I need to mind my language when talking to a lady. Was this really that big of a deal? I grew up in Andheri, went to school and college in Juhu. This girl was clearly from a well to do family since she had her driver. Not once did she apologize but instead made the entire thing about me using the F word once.
