On my recent trip to Oz, the groups of Chinese were to be avoided. At places of interest they crowded forward without consideration of others. On board aircraft, they had no concept of quick boarding, how to stow hand luggage, and would swap seats on a whim. They talked loudly and stood up when the seat belt sign was on. The CC knew that there was little they could do as none spoke English and clung to their guide to the exclusion and hindrance of other pax.
