Well, I do it in Cessnas all the time...
But yeah, I have seen many JAS A300s (now JAL) perform that very same maneuver, but I think that it is type related. I have flown in several A319s and a few A320s, and the flaps and slats both go down.

I've flown on A300s many times and several of them took off without flaps extended, just the leading edge slats. The wings are so efficient that when conditions are right, like a lighter load or cool weather, they can take off in that configuration.
I experienced this on both A300B4 and -600R variants.

OK here is the explanation:
There are three S/F positions (Slat/Flap) for T/O:
1) Slats 15 = Slats (only) extended
2) Flaps 15 = Slats fully extended and flaps to 15°
3) Flaps 20 = Slats fully extended and flaps to 20°
The crews usually select the optimum T/O position which is (I admit a little simplified for all the laymen around:
The higher the temperature is and
the higher the airport elevation is and
the longer the runway is
the lesser S/F position is selected
