This sounds like a communication breakdown – and a reminder to always get an offer in writing.
Probably broken heart syndrome.
The boss wouldn't want a drunk employee in the office, would they?
It would be a workplace distraction.
The employer probably received too little Vitamin D.
Reasonably, how you could expect the employee to get to the office in that condition?
Dogs are family! And you wouldn't leave a family member to go to work if he or she was in the midst of a nervous breakdown, would you?
Actually, broken heart syndrome – cardiomyopathy – is a real condition. A severe dose of adrenaline can stun the bottom half of the heart, causing it to stop working and send the other half of the heart into overdrive. This condition probably didn't occur in this employee's case.
Let this excuse serve as a reminder for everyone to watch The Birds, so this won't happen to you.
