As a waiter, on any given day you want to spend the minimum amount of time doing the “required” things, so you can spend more time on things that dont mediately require your attention. That is to say, clearing a table faster lets you give more wine tastings, or spend more time having a chat with a table when the time comes for it

This, of course, means that a minimum amount of trips to the kitchen with dirty plates is preferred. No matter how much of the “stacking” phase is removed, it will never make up for another trip it may cause

You might see what I’m getting at, but to put it bluntly, I have never had a table stack their plates in a way that actually helps - it’s always caused a second or third trip

What’s more annoying is that the person in the picture has clearly never had the opportunity to ask a waiter (off shift) about what they think (as they would very roughly disagree with them), yet asserts that people who don’t agree with them are in the wrong
