I used to work at Nordstrom when I was about 19....every sales associate in every dept. has a 'Personal Book' where they write down the names, numbers, addresses, and purchasing info. of their customers..usually it's reserved for repeat customers, but some SA's put everybody in it. Then, it's usually a requirement for the SA's to write Thank You notes to the customers....I did mine on down-time...a tedious little thing to do..but worth it; many customers are really touched by the gesture...and since we get commission, it's quite beneficial, too!
