It happens to all of us however it has been happening to me alot lately. Twice last week I am calling a customer to tell them I will be arriving soon and ...."sorry but...." Now I have a big hole in the middle of my day with nothing to do and my over head is still adding up. Thanks fakes I lost $450 last week , $200 already this week. I know people will suggest getting a deposit before I arrive but if someone asked me for my credit card number to hold a appoinment I would LAUGH and hang up the phone.
