Domino’s pizza asking for SSN?

If you’re ordering a Domino’s pizza, that’s your first mistake, but beware the following, via Consumerist:

[Consumerist reader Brent says] the Domino’s dude wouldn’t let him pay with a credit card unless he offered up his Social Security Number or driver’s license number. Since Brent was smart enough to know you only give such information to Girl Scouts and those guys who go to door-to-door selling magazine subscriptions, he checked it out with his local Domino’s, which told him the nosyness is store policy.

I’m not sure if there is a problem with giving the DL#, and this is not confirmed to be happening here in Sacto, but still, caveat eator.
