I only had one issue.
I had a regular client that was a referral from someone else, and she was great the first three times I went to see her. We'd talk, I would cut her hair, play with her dog, and she would pay me. Fine and dandy.
Then, when I was 8 months pregnant with my son she calls me to come over to cut her hair, as it was her birthday and she was going out to eat that evening. So, off I went. We talked, I played with her dog, I started cutting her hair and halfway through the haircut she asks me if she could pay me in a few days because it was her birthday and she had to pay for her birthday dinner, et cetera. I thought, this woman is a bit simple minded, pretty much stays at home all the time, I felt compassionate for her. At this point, what is going on in my mind is, why did she not ask me before the haircut? Why after I was well into it?
So I agree, and ask her that she pay me within two weeks. She agrees.
I call her up after three weeks, and ask her when can I expect payment?
Then the excuses came, and I explain to her our initial conversation, that I wasn't to be even working due to strict doctor's orders, I risked my health and my son's health to cut her hair b/c it was her birthday, that I expected her to complete her end of the bargain and pay me for the services rendered. She agreed, and we set up a time for me to come over.
I knock on her door, and thought she would just hand me the money, and asked me to come in. I little bell went off in my head, but, I thought, she was okay before, I can handle myself.
Not only did she scream at the top of her lungs, she got right in my face and started threatening to hit me, and I had to try to calm her down. Telling her she was right, agreeing with everything she said, inching myself to the front door. She finally handed me the cash, and I thanked her very much and told her to have a good day.
Would you believe this woman wanted me to cut her hair again a few weeks later, and that she was sorry for terrorizing me? I didn't return her calls.
In trying to think about how I could have avoided this situation, the next time this were to happen, I should have said when she asked me to pay her later as I was in the middle of the service, "sure, I will come back and finish the haircut when you are ready to pay me", promptly pick up my things, and tell her to have a nice day.
I could have just let her get a freebie for my own mistake of agreeing to it, but it came down to an issue of respect for me, not the money.
Is this an odd situation? Yes. In the years I have done mobile work, I did not expect it. Moral of the story is you have to always think of the unthinkable, and have a plan of action just in case.
