A guy wearing sunglasses asked me if I knew if a certain movie had a sequel. True, I didn't know instantly, but I searched around -- Google, IMDB, etc.
Because I didn't know instantly, he said-- let's go with you don't know, and walked away.
Then a man about 50 asked if I could find him books on I don't remember what. Again, I didn't know instantly, he got impatient, and he said I'm going to go find the restroom while you are looking.
