Saw a kid lick the floor

A couple of days ago I was on register, just got finished with my last customer and looked over to see a maybe 5 year old little boy LICK THE FLOOR. And it wasn't a little taste, it was a tongue flat on the floor super lick like a foot long MULTIPLE TIMES. The mom paid no attention. I just stared, I think I was in shock. My coworker said "Welcome to "store street name" we have floor lickers!!" 😂😂😂 Gotta love working at Aldi, never a dull moment!!
