If this was a playground or doing normal childhood activities, then yeah, but this is a fucking Culver's (I think)... This is not normal.
Are we supposed to take OP at their word or something? "Guys there's a kid working fast food! I would have taken a picture but it would have been weird. My Canadian girlfriend who was in town that you all have never met urged me not to!"
You take photos of extraordinary sights. I'm sure the shitheads who have allowed this to happen would agree with you since they want to normalize it.
I'm hoping there's a legitimate, innocent reason for this.
