The not "mingling" with the cabin crew is actually an advantage....! All these countries have a female population that is more than willing to mingle with you that it is not connected to the Borg collective of the company so Why bother?
Not saying that they like to gossip......, just want to point out that they have a very effective system of gathering and distribution of information and that the cabin attendants are usually the best source of intelligence gathering of the company......, the least they know about your personal business the better!
Specially those that seem a little more "westernized" and that tend to make fun of their anal retentive Asian ways...., those are the first ones that will transfer everything you say back to some head honcho....!
