There's a Good Idea Here
You've hit on a great idea for a flash series, which is relating the funny stories of goofy and crazy customers. My rating is based mainly on the humor of the story. The rest of the flash is very rudimentary: graphics, sound, animation, etc. The quality hovers somewhere just above spam. If you are not a flash artist by trade, which would be only a guess based on this piece and your previous submissions, you should find a voice actor or two and a talented artist/animator to work with. Just this story alone, with the right voice work and animation, could easily be a 9/10.
