I always think it's funny when the Enterprise turns up at a planet in Federation space and Klingons or Ferengi turn up and basically say
"
WHAT ARE YOU DOING HERE ? "
Obviously you're in the wrong place and attacking the Enterprise in Federation space doesn't look good does it...
Speaking of Ferengi - they must be so fun to write for. They're just SO frustrating and annoying.
Like that episode with The Stargazer and they basically PRETEND to be giving the ship to Picard for no profit. Then when it's CLEAR they're being violent to Picard
they go " HOW DARE YOU !! WE OFFER YOU A GIFT FOR NO PROFIT AND YOU ACCUSE US OF TREACHERY ??
"
They're just so annoying
And any new tech the Federation are using - the Ferengi or Klingons or Cardassians always think it's a new Federation doomsday device specifically designed to wipe them out
