Ooooh! He made a comment to her about how he's "not jew-y" so she should order whatever she wanted. She was Jewish. Spent the rest of the evening in silence as he went on about how his ex girlfriend was anorexic and "so annoying about food." He was happy to be on a date with a woman who could eat like a normal person.
Edit: one of the only times she spoke was to respond that she was Jewish. It was a quiet night in my restaurant and I was nearby doing sidework. She seemed like a very shy person.
