No, it was a serious question. Appreciate the answer. I figure if a VFR tower and receiving a request that's beyond the scope of what service you provide, that there's really nothing else you can do but recommend to the pilot who he would need to call and maybe even pass the frequency to him and make his request with that appropriate facility.
Regarding LOAs, its very interesting how different facilities deal with operations within their airspace, and how it's seemingly facility-specific, with no real standardization. And I've only learned this while having to work out procedures for our aircraft to operate within certain airspace areas in both Class B and C airspace within our working area here in AZ. For example, P50, as a rotary wing and if going into/through PHX tower's airspace, you can simply fly beneath the Class B shelf, and contact PHX tower directly for transit or landing in their surface area, while never having talked to P50 itself. However, at U90, it is verboten to fly under the Class C shelf and contact TUS or DMA tower directly before entering their surface areas to transit or land.......you must contact U90 first, even though most of the time all they do is issue a squawk, radar ID you, then hand you right off to TUS/DMA tower anyway. Almost a waste of time contacting them in the first place, it seems.
