What's the actual right order for building a burrito?

I've worked in three different kitchens and every one had a different sequence. First place did rice, beans, protein, salsa, cheese, guac last. Second place put cheese directly on the warm tortilla so it melted. Third insisted wet ingredients go in the middle so they never touch the tortilla.

All three swore theirs was the only way. Is there an actual reason to pick one, or does it only matter that you're consistent?
