This is marvelous. Not only does it make one wonder exactly how on earth the man could have ended up with frozen tea, the third-last paragraph contains some marvelous descriptive text, and sarcasm. Kind of reminds me of Wodehouse, or maybe Douglas Adams.
Silly and fun, but seeming to hint at something more odd that neither of them are really acknowledging or perhaps is so mundane it’s not worth mentioning. I got the ’Hitchhiker’s’ vibe too. I also like the assistant’s name being a slight variant on the infamous strongman Samson’s name.
