I'd sort of expect older people to be _less_ uncomfortable about it. Back in the day you bought more things from from smaller stores with proprietors who might recognize you and remember what you purchased last time. I'm pretty sure I've old movies where someone walks into a store and the guy behind the counter says something like "Hi Bob, we've got a new order in of those Foozits you like!" and Bob is embarrassed because he's with someone who he didn't want to know that he bought Foozits. I'm not very sensitive to privacy issues for a HN reader, but I know that my parents positively want to have personal relationships with the entities they buy things from.
