Given that the average snooker club table is not 100% level and does not have a cloth without dirt and other obstacles, it's super frustrating to work on your snooker technique when you're not sure if you're doing it wrong, or if it's the table.
Not unlike when you're writing custom Drupal code and it's not working and you're not sure if you're doing it wrong, or it's Drupal (core/contrib/...).
