I am FSS. There are two issues; first that unlike Tower, Approach or Center controllers who have one to maybe three frequencies to work at FSS Inflight I'll have seventy to a hundred radios over several states and few pilots have any idea that anyone else is also calling me, second is that we're General Purpose and in effect a dumping ground - 10% of the callers want to use 110% of the available resources as when their on-line filing of a flight plan has gone astray or they've missed their window for Customs, a commercial carrier schedules three or four aircraft to depart at the same time across the region so they all call me for Clearances at the same time or the instructor has handed his ESL student a diversion that they'll stumble through - now FAA and LM are adding on the occasions when pilot's want and need a detailed interpretation of severe and changing weather all on the same frequencies ...
Other than that it is a pretty kick back job!!
In all seriousness I have been visiting stations when the fan went into overdrive flinging.... stuff
every which way. Maybe I'm old school but I sometimes long for the days when there was a local FSS within 75 miles of most airports around the country.
