Speaking as a Southerner, you are 100% correct. Aside from the particulars of the pronunciation, the terms themselves are totally alien.That's how we do it here, but it's more a "lah" on the end than a "luh." Most of these Northeastern dialects come from a common root -- the hash of European accents that clustered around the docks in the 19th century -- and I imagine the subtle regional nuances are only distinguishable to those of us who live here. To a Southerner or a European, I imagine we all sound like nose-talking characters out of a Warner Brothers potboiler in 1933.
"Bubbla" for "water fountain"? In my entire life I have never heard that word. I can imagine an encounter with a New Englander:
"Where's the bubbla?"
Where's the WHAT!?"
The "bubbla"...
The WHAT??
