This happened two days ago in my store at about 1pm.
I'm standing at my spot trying to sell my product when in the distance I hear a kid scream. Pretty normal sound in retail. I continue pushing product. A few minutes later I hear the scream closer and louder. This kid must not be having a fun day.
A moment later the kid is in the next aisle to me and I hear an ear piercing shriek followed by a scream. While I ponder if the kid has autism or not and serve another customer I notice the kid isn't stopping. I can't hear any scolding from the parent so I guess the mum or dad is just letting the kid wear itself out.
Suddenly the kid stops mid-scream. Papa bless. I go back to serving and then I see my team lead rush over to my manager. "Hey we need maintenance with a mop in the fridge aisle. A kid just vomited."
The kid screamed so hard he/she vomited all over the aisle. I can't move from my spot because of the location of my product so I put up with the smell of kid vomit for about half an hour. Fun times in retail.
