Under what circumstances travel or per diem allowances are not due during a business trip?

Travel allowance is not paid if free transportation is used, if the person is at the place of business trip for another reason, or due to their fault they delay their return after completing the official task.

Per diem allowance is not payable if the person is provided with free food all day during the business trip or if they become sick and are accommodated for treatment in a healthcare establishment.
