Pay it forward

So today I was getting my daughter some things from the store. I was a few dollars short and the woman behind me payed for me.. I did offer to go to my car but the cashier was super rude, and said then I'll have to put all my stuff back and reshop.. So the lady behind me offered to pay the rest . Offered to pay her back and she said no no no. Some people are a godsend🙏🏻
