I think English is quite easy to learn; the pass mark is very low. Chinese, for example, is much harder. Most native Chinese take a few minutes of learning before they can talk to a stranger, which is one of two, ok, three frustrations when queuing, four frustrations when queuing in McDonalds in Hong Kong. The last is most obvious - the food is dreadful; and the third becomes obvious when you get your food and discover that all the “empty” tables have someone sat there reserving it for their friends in the queue. But before you start looking for a seat, before you start eating the polystyrene containers, first of all the guy in front has to exchange some pleasantries with the server to come to grips with one another’s’ tones. “Aye, they’ve got the hang of it - ‘cheeseburger and fries’” but no! Chinese people are interested in food - “is the same pickles in the cheeseburger as the quarter-pounder? What oil do you use for the fries? Can I have the bacon double cheese burger as a double bacon cheese burger?”
Im normally so hungry and grumpy I sit down at any table and wolf it while their mates are still negotiating their sauces and soft drinks. And get up queasily, remembering why I stick to Chinese restaurants - you can get beer there
