Okay. Let me try to salvage this obviously ill-conceived joke. Probably a bad idea, but here goes.
I have generally gotten very fast turnarounds on Amazon shipping speed. Like, stupid fast. When they say two-day shipping, they do not fuck around. I am unused to considering Amazon slow.
I happen to enjoy similes that compare things to absurd situations, such as, well, Amazon warehouses working fast because of summary execution as a motivational tool.
For an extra hit of realism, I'd heard that Amazon has some pretty bad warehouse turnover because they actually do work them pretty hard in those things.
I felt I was clear enough at the beginning, and I didn't know what to do with a request to clarify something that I thought I'd already worded straightforwardly. To respond to your actual question, I wasn't sure what to clarify, so I asked what I'd need to explain in what was, in retrospect, kind of a dickish way.
I hope that this thorough proof that my sense of humor is a vestigial organ in a jar of formaldehyde on a shelf somewhere has helped.
