Well the thing that you're forgetting Ahh-40612... Is that you ARE still human, and you CAN forget to mention the fact that there's no speed control!!
As I am a regular into LGW, I've asked for the same as well on a few occasions... - "Especially when It's quiet as a mouse on frequency (doesn't happen that often) or when comming back into LGW on very social (NOT) hours."- And not being told about any speed control.
I'm sorry but I will continue to ask for "any speed" if nothing has been said on these occasions as described before. Which IMHO seems fare
Cheerio
