Thai normally do not know what is cheese.
Most probably because cheese is not in their standard Cuisine. Similarly, many people on this planet might not know what a good/bad wine, whiskey etc is. Are all people familiar with the Chinese food which is consumed by over 1.4 billion people?
Food is something very specific to each human or group. What is good to one might be unpalatable to another. For example, I don't like to be even near the smelly cheeses however expensive they are, nor would I touch Caviar! But I love cheddar which some classify as thrash! Tastes can be 'acquired' if one pleases - but it does not mean that eating this is hi-so and not eating that is lo-so!!!
Just my 2 cents!
