It just ruins ur mood when u see stuff like that. I seen a pregnant woman, her dude carrying a sleeping or trying to sleep toddler while pushing a newborn in a stroller at 2:30ish am. It’s zero fun for them, they always look exhausted and the selfish parents couldn’t care less.
Aside from that I never noticed any other reason for a kid to be there after hours.
During the day there’s multiple restaurants open.
