Being German who lived in other parts of the world myself, and someone who likes food and considers the typical German BBQ an abomination I can feel your pain.

But is this not more of an example of you wanting to do things the Brazillian way rather than German's unwillingness for you to integrate? At any rate, the Nackensteak guy is a total dick!

Also don't forget, a lot of those Italian, Turk, Greek, Spanish and Polish coworkers may well be Germans...
