Always remember you may not know the circumstances another person is dealing with. An act of kindness, even the smallest and simplest ones, will go much further to improve any situation than almost anything else you can offer.
When dealing with a distraught person, and remember a customer is a person first and foremost, always remember to be at least considerate and that small act of kindness may be the key to resolving the issue at hand … and even if it doesn’t solve the issue you will see that it will have made it much easier to deal with.
