Debit or credit?

When you pay a good with a card, you have to be very focus because of all of the questions you may give an answer.
Firstable, would you like "debit" or "credit"? In fact when we say in France we pay by "creditcard", we are wrong, we have simple "debitcard".
After that "cashback or no?", this is quite convenient, you may ask for $30 in cashback.
It's not finish, one  month ago it was "would you like to support breastcancer association by giving 1, 2, 3 or more dollars". Right now "would you like to give money for the aftermath of the hurricane Sandy and help people in New Jersey and elsewhere?"
You have a last one "is this amount correct?" yes or no. Each time you push a button. Sometimes I make a mistake at the end by pushing "no" and I have to do it one more time....
