but you know the locals culture. Fr the liberals, they are more understanding about he expats but for the conservatives, the culture will come first or foremost.

The volume of alcohol really depends on a persons capacity to absorb alcohol in their body. If to others, common to western people, a glass or two will be normal and won't even be manifested in their look. But for some who are not "that used to it". a glass or two is still ok but the manifestation on physical look matters. MAny becomes to "reddish" and the smell is very profound. So that is the danger of alcohol, it maybe moderate may have trouble with authorities specifically if you are driving.
