If everyone could deny purchases just based on wrong signature, then everyone who uses those horrid miniature electronic signature pens at the self-checkout counters at my local Ralph's (Krogers' brand in SoCal) could be disputing most every purchase there. I compalined to the person monitoring the self-checkout area that I couldn't sign despite many attempts (the electronic pen kept turning signature into incomprehensible garbage) and he said just to try and click accept no matter what the result! And they never fit them, so now I have to do that every time!
