How can I get WiFi without paying monthly?

I'm curious, how can someone access WiFi services without having to pay a monthly fee? Are there any cost-effective alternatives or methods that can be employed to achieve this goal? Perhaps there are certain devices or services that offer free WiFi access in certain locations, or maybe there's a way to leverage existing connections to create a makeshift network. I'd love to learn more about the options available for those seeking to save on WiFi expenses.
