She returned with a printed receipt for the balance and told me that I would have to use all of it for the tip or none of it.
I decided that $14 for the tip was not going to work.

It's possible that 1 she didn't know because she didn't have any gift card experience or 2 she was hoping to "force" a bigger tip. I'd like to assume #1, but these days, my first thought is usually #2.
