As discussed in previous posts their is very little western influence in Bhutan and, despite understanding this, the extent of the differences between Australia and Bhutan could still come as a shock. For example, there are no American fast-food restaurants in Bhutan; not a single Mcdonalds!
I personally do not eat much fast food but they are such a staple in Australian scenery that the disappearance of that could be a slight shock. The lack of understanding of a fast-paced western life-style in Bhutan could very much be difficult to adjust too. No bustling around, attempting to find time to eat, instead, a much simpler more relaxing rhythm.
Not having a big city or tall office buildings or people in corporate attire rushing around will probably be a welcomed change, however. Instead of focusing on work or the future tourists could have an opportunity to live in the present and enjoy time appreciating the natural beauty of Bhutan and simple living away from the pressures of western society.
In this instance, I think the culture shock will be a welcome change and embraced by many travels. Far from trying to minimise it, I think people will attempt to adjust to the Bhutanese style of life. Appreciate what the Earth has given them, live to be happy not to make money and live in the moment. Bhutan is a nation of wisdom and tradition and us in the West have a lot to learn from this humble country.
