I'd been courting a new client for weeks, re-sending 'misplaced' documentation, slide-show presentations, and showcasing our upgrades versus her current service. She was interested throughout the process, but in the end cited relationship loyalty and opted to stay with the provider she'd been using. I'd pitched her, walked her through the benefits of our service, made the most compelling case I could, but in the end nothing I could say short of 'the other guys don't stop for old ladies' was going to change her mind, so I left her our information and my number and told her the offer and terms would stand if she changed her mind.
