How proud people are about their phone numbers. I work in retail and we have to ask for phone numbers to get their discounts, and they'll start off all quiet and sulky through the whole transaction, but the minute I ask for a phone number they perk up straight and the way they say it....as if that was the only thing that mattered in the transaction, their tone is almost boasting as they read off their phone number...and then they go back to being rude and sulky.
