So you managed to keep your feet on the ground (instead of parking them on his desk) while being interviewed by your employer and he invites you for a night dinner. (for a good reason)
The dinner runs smooth until you decide to vomit into the decolletee of your future bosses wife.
I guess you'll be fired before even being get hired. (lack of general education)
BTW, the man telling me about the bomb craters in our autobahns was an American citizen.
Believe me, we won't enjoy people like him visiting Germany as well as we won't enjoy dogmatic persons!
