It just shouldn't need to be the case that I sacrifice privacy for convenience.

Years ago shopkeepers asked you what you wanted and then they went and got it and packaged it for you. Then it became the better option to let you choose your own items and we'd just deal with the shopkeep to pay. This way more people were served simultaneously and everything went quicker. Imagine if you had to tell the shopkeeper the last time you cranked yourself or what size your living room is in order to progress to this more efficient process.
