I through out years ago it served no benefit to me either on getting business for me or when engaging the customer they weren't that interested as they had never heard if it, the straw that broke the camels back was when an old customer said to me that they weren't having me to clean the carpets this time as they had found another ncca cleaner who was cheaper.
I'm not going to push the ncca benefits for others to benefit and me to lose out.
