Carnage,
Antigua wasn't asking to jump the queue, but merely emphasising that he'd like more seperation in order to prevent you having a very disrupted morning.
Appreciate that, but see my previous comment.
If lots of inbounds were to ask for increased spacing, for whatever reason, it would very quickly sink the landing rate.
By all means if you find yourself short, but within the legal limit, ask for an extra few hundred yards in front. Just try not to make a habit of it
