A customer who wants to thank you for your willingness to be just as helpful if the job to be done is small, as when it is large.  Changing a ceiling light bulb is small for a person like your man, Bob, but for a couple in their 80’s and a bit shaky, it’s downright dangerous.  Thank you for you caring and for the bill which we hoped would not be large and were pleased when it wasn’t.

Best Regards,
John H.
