Flash Me!

It's helpful to a) actually show me what card you're using to pay and b) if I ask you what card you're paying by, if it's credit, telling me 'credit' tells me nothing. I have to press the button for the specific card one on my screen. If I ask you which one and you repeat 'credit' I'm going to want to bitch slap you, especially if you do this more than three times!
