Musli aint very healthy so give it up.  Quite glad (that's common) about #5. I'd have expected anything to do w/ chalga (perhaps you  like the cheap chalga chicks, though?)

As for non-speaking English, also slightly astonished but very slightly, my gf observation was the same, actually.

However, as for post office: hell, dude, what do you expect the lowest salary employees to speak English. Be real.

Possibly grannies "conserve" the stuff - jams, pickles, etc.

The numbers in Sofia goes like that: odd one side, even the other. The number value (usually) increases from the downtown to the outskirts.

Disclaimer: I might be off since I don't live in Bulgaria for couple a years.

Cheers (good sh!t)
