I voted return and pay, however, when I was in high school I was shopping with my then boyfriend, when he became very ill. I walked with him to the restroom area and waited. When he finally emerged, he looked aweful and we left the store. I realized once we got to the car that the greeting card in my hand was never paid for!

I was so embarressed and wanted to go back, but the bf was in so much pain that we left. I'm sure karma kicked me in the butt for that a few times.
