SD-Would You Be Offended If A Man Wouldn't Let You Fill Your Wiper Fluid

Okay today's social dilemma happened to me yesterday.  And I wasn't quite sure whether to be offended or grateful.   Yesterday on the way home from work, I stopped at a gas station to fill up and to buy some windshield wiper fluid.    After I put the gas in, I opened the hood of my car, which is a Lia Hyundai Tuscon.   I got the windshield wiper fluid I had just bought and was opening it up when a man came over to me who had been putting gas in his car at the pump across from mine.   He said, woah, woah woah, what are you doing there m'am?  I said I'm about to put wiper fluid in my car, can I help you?   And he said, a woman should never have to do that, let me do it for you.    And I said I was fine and had put wiper fluid in my car plenty of times.   He persisted and said my husband should be doing this for me.  Now he wasn't an older gentleman, he was younger than I was, probably around 40ish.  So I said to him, Sir, I'm sure you're trying to be kind, but really I don't need a man or a woman for that matter to fill my wiper fluid for me.   And he said, a woman should never have to get her hands dirty with this kind of stuff. I  got tired of fighting with him and I let him put the wiper fluid in the car for me, thanked him, and off we went.  To be honest, I really didn't know whether to be grateful or offended.   What would you have done in that situation?   How would you have handled it?   Let me know on the 98-3 TRY Facebook page.
