If beg people for something to drink at the stop light

You can only whisper in a harsh croak. You approach the first car, it has three teenagers in it. Two boys in front and a cute chubby girl in the back. You croak out your request and they all give you the empty big gulp cups they have finished. The bottom third of each cup is crushed ice. You think them kindly and begin chewing up the ice chunks. Your throat fills better and you stop choking.
