We had a mom who asked us if she can get another client's name and address so she can send a personal thank you letter to the other mom.  The other mom had lent her a mini iPad so she could use it to book a hotel for their stay so they can finish up their treatments at hair fairies the next day.  It was very kind of both moms (who didn't know each other) but they both understood what head lice entails and the stress they can incur. It just goes to show that a kind gesture can go a long way even for head lice treatments.
