Yep, I think people should check first but it kind of depends who it is as to how 'offended' I am.

There's a woman in the milk bar who always gives DD something when we go in. Sometimes it's junk like a mini bag of lollies and sometimes it's healthy like an apple. Now, I don't mind really because she obviously enjoys seeing DD and I think she grabs the first thing that comes to mind.

On the other hand, with friends I do mind. I had one who said, "what she's not allowed to have biscuits yet," when DD was only one. I think she wanted to use it as an opportunity to make a point that I'm an over-protective parent. I did mind that because she should have known better and when I said no, not questioned it. If it had been the other way around, I would have apologised for offering something that someone else's child wasn't allowed, not got huffy about it.
