the right (accepted) things to say when talking to a client, customer,
passenger, etc. The exercises below will help you learn and practice the
right way to talk to your customers in English. They will train you to
sound more "natural" when speaking English, which will lead to a better

If you work (or are looking for work) in a restaurant, cafe, bar, etc.,
and want to learn the common English terms and expressions that are used
in such places, these exercises are for you! They will help you to
speak better English, to use proper words, and to communicate better
