Reader Lorna Herf and her husband — the ones who walked away from paying cash for a BMW because the dealer demanded a thumbprint — are taking a spin in the media fast lane. They were on ABC 7's news last night and I know of at least one other station that contacted Lorna after Sunday's post on LA Observed. She emails: "People are so upset, and I hope the dealership is listening. This little story has taken on legs of its own. I'm having a great time reading the discussion in my comments, they are intelligent and thoughtful, and I'm learning many more reasons why this just shouldn't be done." She has received 75 comments in the discussion at her blog, Lornamatic.
