HI,

When I pay for delivered pizza from a local place on my Visa, the receipt I sign has my subtotal, a blank for me to write in a tip, and a blank for the total. I've been writing in the tip and addding up the total, but not giving the delivery person cash...do they take the tip off my Visa, or do I give them cash even though I'm adding it up on the credit card receipt?

Please help. 

I did not find the right solution from the internet.
