can owner of router know laptops location?

if someone connects to a router and uses the internet, can the owner of the router

  1. find the laptop’s location?
  2. see the content of an email that the laptop owner views?

does it matter if wifi is owned by the city or a private entity like mcdonalds? there is an open wifi spot in a city close to me and anybody can connect to it and I find it hard to believe that it cannot be tracked.
