Given my radical views on privacy, why do I find the idea of clerks greeting me by name and recalling my preferences so off-putting but have no problem with the prospect of computer indexing of vastly greater and more detailed information? Possibilities:
1. I don't like the idea that an actual person has been contemplating me and my actions, especially when they are trivial. To the extent that I consciously shape my identity, this reminds me that what I view as minimally performative actions are part of other's main conceptions of me.
2. The person comes off as stalkery. (May be a function of my gender.)
3. It makes me feel obligated to be friendly to the clerk and I would rather just hand over my money and get out with a minimum of personal cruft.
4. It implies intimacy, and I may not be comfortable being intimate with this person.
