Yeah I read the thread and I still don't see the "stomping."
I don't know where this "quote" came from, but I'd bet that's an isolated incident and it needs to be reported.
One runway ops at FLL would necessitate larger arrival gaps to get departures out, especially if they've lost the ability to use Line Up And Wait. LUAW requires an additional controller in the operations area at many facilities.
Also, I don't know what their IFR release situation is with Miami approach. If they have to call every time, or if they normally have automatic releases. Either way, a reduction in staffing at Miami Approach could affect FLL tower's ability to move airplanes, in addition to FLL losing staffing themselves.
I'm not saying that's the situation, but I think we deserve a little more credit than being accused of stomping our feet because things run more slowly when we're short staffed. I can assure you, nothing pleases us more then moving airplanes off our frequency as fast as possible. If you were working a checkout line at a retailer, would you consciously want the line to build ever larger while the occupants got more and more pissed?
