Alcohol hurting the relationship: France cancels lunch with Iran

Alcohol use can cause problems in any relationship, even those of the diplomatic kind. 

This week French President François Hollande canceled lunch with Iranian President Hassan Rouhani for asking that wine not be served during the meal. The action calls into question how one provides hospitality and relates to the proverbial "other." 

It is worth noting that the Iranian leader also asked for halal food, similar to kosher, and what President Netanyahu asks for when in town.
