Parents who bring kids to fancy restaurants and places
I laughed when the movie poked fun at that.
Parents who bring kids to restaurants, movies, establishments for adults are rude and inconsiderate. Recently I had to endure an awful parent/guardian who brought a baby into a R-rated horror movie and try to rock and shush the wailing baby throughout the movie.
Seriously, get a babysitter or don't go out and disturb others. There should be no babies allowed signs in some places or some sort of fine for parents who break that rule.
One time I was at a getaway inn where adults went to relax. I didn't know children weren't allowed, but a rude couple snuck their two children in for whatever reason and were promptly kicked out the next morning. The supervisor of the place came by after to tell us he didn't know and apologized for whoever heard the children running around and disturbing others.
I hope more places take note!
