Do you think this is appropriate ??

I was at home goods today checking out. The cashier asked if I would like to make a donation to saint judes children’s hospital. I politely declined. She said if but you just donate 15 cents you can even out your bill. I look at her and said ok to get her off my back. I think it is so inappropriate to ask again after I already said no. It’s my money. I make my own donations throughout the year and I don’t need you pressuring me as I’m doing my Christmas shopping. Like am I the only one who thinks it’s inappropriate of an employee to pressure like that?

Side note: Obviously 15 cents is nothing it’s not that, it’s the concept.
