Hey radar guys, don't forget that if our pilots friends don't fly their assigned speeds on approach and start playing catch-up, they'll be hearing this phrase a few times: "GO AROUND, I SAY AGAIN, GO AROUND, ACKNOWLEDGE!" I'm sure a few of these would start to focus their attention. I know this is much easier if there are no departures and you're packing them in and that missed approaches are a bugger with one lined up ahead for departure at SS GW and KK, but what can you do? (other than not lining one up ahead in the gap, in which case the non-complier "wins" with a timely landing clearance).
PS: this isn't ATC getting all ar$ey, this is a reality of flying faster (or slower) than you assigned speed
