Thanks for you comment,<p>would you tip an oncologist who gave you a second opinion for free? Nope. You would just be very grateful.
- basically, this is a reason why it&#x27;s called &quot;Tipping culture&quot;, when you go to a restaurant you have a choice to pay or not pay a waitress there, and nobody can force you to leave tips, right? - But, usually people don&#x27;t say, that the service was super nice and that&#x27;s all :( normally they leave tips.<p>Here, it&#x27;s the same. Previously, you didn&#x27;t have an ability to pay developers who helped you and now you have it, so it&#x27;s up to you to pay or not to pay. It&#x27;s all voluntary.
