"Ta da!" he said with the flair of a magician successfully performing a magic trick. "Fizzy drinks! Take your pick! We have cola, and lemon-lime, and root beer, and this stuff!" He selected a bottle of Dr Pepper and twisted off the cap, shoving it into the pocket of his jacket for safe keeping until he could recycle it, later.
