Because the credit card is unobtrusive, easily concealed and no one wants to loose their life over a fudge round. In my city a man lost his livelihood because the cook put pickles on her hamburger, so she had her sister go out and get her pistol. She shot him and paralyzed him. His 3 year old daughter still has a father but he is perminatly a quadriplegic. All over pickles on her sandwich. Good grief. I will let you guess what ethnicity this person was.
