<human>: 3 kids all under 7 were just terrorizing my store while the 3 older women looked around and did nothing. When the middle child (around 4 or 5) whined at the counter for a sticker book the mom told her she had money and could get it because she had her card. The little girl was like "where my card at?" and the mom handed it to her. I was like o.0 ok... but since the charge was only for $1.06 and I had told the children multiple times not to touch things or not to run behind my counter and the women did nothing, I figured it would be pointless. She handed me a YMCA card that served as her ID and the card went through. When I tried to hand the card to the mother with the receipt to sign she was like "no, that's her card". So I handed it to the child and made her illegibly sign the receipt while I had about 4 people in line meeting my confused looks with confused looks of their own. 

I read on credit card websites and it said no one under 18 can be issued a credit card as it's a legal document, but the child can be issued a card in their name on the parent's account and the money all goes to the same place.. so maybe that's it. But I'm very confused and wondering if I should be calling Visa and my boss about credit card fraud or parents about to ruin their child's credit.

Give me the gist of the text in a nutshell
<bot>: a mother just made her bratty and loud child pay for a $1 sticker book with a credit card in the child's name. The child signed the receipt and the people in line all asked me if that was even legal.
