Narrative:

We were approaching departure time; and the aircraft had not yet been catered. At once; the caterers showed up with 2 trucks; one in the forward cabin; and the other in the aft cabin. All was catered before departure. The doors had been closed and armed; with the jetway pulled. Unbeknownst to us; a truck showed up at the rear of the aircraft. We were in the aisle doing our safety demonstration; at one point in the demonstration; we heard a loud hiss. The aft slide at 2L had been deployed by the caterers. We ran to the back to see if everyone was ok.
