Re: Let's assume you were working in Pakistan.
Dude if a big company has hired you as their relationship manager, chances are you can handle relationship management fairly well. In the scenario that you have given, unless the guy is a professional qasai obsessed with chopping and eating meat, he should be able to find quite many areas of common interest. Relationship management could be way beyond meat management.
If your scenario was - these are two different people, who would you rather spend time with? Answer to which could be the guy you have more in common with.
