Or, apparently, the wrong tone of voice (I wonder if it's just the PM who needs to watch her tone or just everyone we send on a trade mission). Or anything too "politically correct" (a famously elastic term, especially in Trump's case). Or anything that isn't just abject grovelling, really.
And even then, Trump has no problem whatsoever with just unilaterally pulling out of agreements from nowhere or changing policy because he feels like it.
I really struggle to see how we can possibly hope to negotiate anything lasting with someone who is that erratic.
