im confused, how is that going to help them speak better English.
Well, Eric those people are not just 'students' or 'pupils' in the conventional sense of the word. They are business people who are trying to attract more English speaking guests. If you run a hotel or any tourist oriented business, you can only grow and spend money on 'English classes' if you actually are able to attract this target market. So why not provide them with tools and ideas in this area too?
