With all my carpet cleaning i always tell the customer if they are not happy with anything once the carpet dries ill come back at no charge to fix any areas of concern. Yesterday a customer calls back 3 weeks later saying her husband walked dirt on one of the rugs i cleaned and asks if i could come out and redo it. I was about to say no however she is a really nice lady and she said she had recommended me to several of her friends. Anyways i agreed to come back for free , would you guys done the same thing or is this going to far? Is it worth it to gain a cheerleader or a waste of time.
