I've run into people thinking I was being selfish for grabbing something for myself, but they don't know how rare it is for me to do that. I was raised that Mom/Wife got the last. DH and I got married at 18 and had kids right away, and money was very tight while they were growing up, so I got use to going without, and making sure that DH and kids had the best of whatever it was that we got.
So for the few times I grab first and hang on tight, DH will often look disappointed and others look on me poorly, but DH is only doing it because he's use to getting first dibs. He does admit that he's rather spoiled when it comes down to it.
