My dominant hand wrist was destroyed 10 months ago (radius is held together with metal, tip of the ulna is broken off, wrist bones were severely dislocated, and I have ulnar nerve damage) and I haven't learned to write with my non-dominant hand. So I carefully signed my name. Signature got rejected by the machine so I was asked for ID. Person who checked my ID said it was very close to the signature on my ID. Should I have screamed "That's racist to ask for ID!" ?
