The boss is quite ill.
This illness presents him with quite a dilemma: Should he lean over the porcelain throne? Or perch atop it & use it for the intended purpose?
The illness is quite horrid, none who see him would wish to be afflicted so.
The boss' throat is raw, his digestive system is bubbling as if it contained a witch's cauldron, his eyes are bloodshot from the continuous involuntary expunging of fluids & stomach contents. The boss has noticeably lost weight already, he will have lost quite a bit more before the illness has run its course.
Despite his outward exhibitions to the contrary, Mine Host has little sympathy for his subordinate.
For the illness is preventable, very preventable.
What was the cause of this illness? Lack of hygiene? Contact with a "carrier"? Bite from a microbe or mosquito or somesuch, that carried the bug?
No. The illness was actually very easy to prevent. Pretty much caused by failure to apply IQ to a given real-world scenario:
The boss had summoned the cook to the office for a "no-coffee" discussion, which culminated in him sacking the cook, subject to a notice period...
... then being as it was just about lunchtime, the boss instructed the cook to prepare him a hearty meal.
