I dont know what to do with this sticky mess, it is all over me and it smells weird, please help

AITA for telling cashier that wasn’t the girls credit card?

Throwaway because husband told me I was TA and want to know before I get home and argue. On phone format is bad.

I was in a higher end department store today (rhymes with loomingtales) and happened to end up next to two teenage aged girls while shopping. One of the girls had picked out a pair of VERY expensive boots and they were both fawning over them. Second girl must have looked at price tag and asks boots girl if she’s really gonna spend that much on boots. Girl with boots says something along the lines of “it’s fine I have my dads credit card I’m not paying ” which instantly caught my attention because THATS NOT HER CARD. I’ve told my son multiple times he’s never allowed to use my card so I’m interested to see how this girl thinks she’s going to get away with fraud but had split up from the girls at this point because they had found something else.

HERE COMES THE TICKLE MONSTER!!!!
