I have noticed that a tub ritual does make the snake realise what's happening as soon as I set them down. It also helps them get into the mindset of "oh hey I'm supposed to eat this and not laze about my tank".
Since I have them out and about in my house with other animals and children etc, I feel it is good to have the snake know this is the only place I eat.
If your snake has not previously been fed in a glass place and its a new home it might be perfectly fine with switching to a new way to eat since it's switching to a new home.
I suggest testing out trying a tub at least once to see if the change works, and if it doesn't, try something else.
If you feel like you'd like to keep feeding it in a tank it sleeps in I would still worry about substrate/ etc, and put down newspaper to be safe. Our babies might be wild animals, but we have to admit sometimes ball pythons don't know how to think straight when hungry and just strike until they hit something.

There is no one really right way to do things, as long as you find what works well with you and your snake. Just like humans they can have their strange habits that you have to learn to work with. I wish you luck with your journey!
