Say you've used a Croc Birkin for 10-15 years and the darling has aged ever so gracefully. It's the only bag you use. And anyone who knows a Birkin can tell that the bag has truly been loved and used. But it is really old and you think it is time for a replacement, to enjoy a spanking new Croc. You carry the bag with you, walk into the mothership or any H store, where you have no prior relationship, show them the bag and tell them how you really need another, a Croc as well (which is almost impossible to come by where I am), sort of as a replacement to carry you through for the next 10-15 years. Do you think they would appreciate your true "love" and appreciation for the bag and graciously oblige?
