I did not know about new pipe. Thank you

That may make sense for the improvement of the restaurant. That data serves a purpose and has a life cycle. It is ok if you process it in an anonymous way and delete it once you are done making over the restaurant.

By no means should it be acceptable to keep it forever for “just in case” nor sharing it. If you are an interiors decorator and your life is designing restaurants, I do not think you need the data to take lessons learnt to other restaurants. Just take a look at your previous designs

When I go to a restaurant, I do not mind that the staff knows me. If I am a regular, I do not mind if they know my favourite dish and ask if I want it or suggest other dish I also may like.

I do mind if the restaurant keeps a note of everything I ever ate and is now sharing that information with dates attached with all restaurants.

What I absolutely dread is if now the restaurant is sending me unwarranted letters with their new menu options.

You share 2 interests with my guts
