I don't even use plastic - I pay cash
Last I looked (been awhile) they wanted my mobe number, you bet - and I don't have one - security by non existence. SMS? I've heard of it, and will not have one until after I get a facebook account, sometime after I die.
They don't seem to understand that not all of us are phone addicts. When I'm out and about - that's MY time, not to be interrupted by any moron who has my number and who is bored and wanting free entertainment from me. I happen to have a car with a cel phone and have no minutes and don't even know the number. No need. If I need 911 - that'll work. Else, bugger off.
