You lucked out man, seriously. Staying calm and being truthfull helped out a lot I am sure, I had a case where I did the same thing in a bestbuy parkin lot, then me and my friend heard tires screach and we looked and a white car with a big anttena was coming at us, so we just booked it behind the building, ran to the family fitness place, and called a ride from there, we got really lucky too.
