Ungrateful much?

Do you think if someone has a babyshower, and nothing was purchased off their registries, and all they receive is clothes , they have a right to complain? Idk if this is against the rules but I saw a post on a forum (may '16 babies) where a mother is complaining and basically bashing what she received . Said she was grateful then proceeded to rant on about how no one bought her a crib , etc and how she had to spend all her savings on a crib etc. Do you think people are obligated to purchase such espensive gifts for a kid that isn't theirs? I wouldn't afford a crib, bassinet etc knowing I have my own kids. It'd be easier for me to get clothes or blankets for someone else's shower. I was appalled at how many other mothers agreed with her and proceeded to complain about theirs too.
