Husband being rude in public

Hubby and I went out to eat tonight. We tried like 3-4 different places before we finally found a place to eat. We both were hangry at this point. Well we eat our dinner and everything is really good...well this baby starts crying next to us at the end us finishing our dinner. Like we were just waiting on the check to come. And he starts bitching super loud about the maybe 4-6 month old crying and how the parents weren't doing anything to comfort him...im like really you're gonna make a fuss over crying when we have a baby who's gonna be here in less then 4 months? He's like if our child is ever freaking out inside a restaurant I would take the baby outside to calm down. Not ruin everyone else's time out eating. Which I totally understand but the crying wasn't even that bad. But I do agree the parents could have tried to care a little more.
