Good advise here, as normal:hug: I am quiet sure that the only reason the salon owner is giving you grief is because you havn't returned her call, so do it, yes she's (in your mind) an old bag, but, as others have said, she wants this resolved and she's probably regretting how she treated you now that its biting her in the bum. Write down all the things you need to say, so that nerves wont make you forget half of it, even if your knee's are knocking, smile when you phone, its a sales trick, smiling streches the muscles and makes your voice sound lighter and more confident. Then just ask for the ladies phone number, so that you can sort this out and reasure the salon owner that you will call her back when the problem is resolved.
Then call the lady, explain as hippy chick said, that doing the service is not a problem, lack of transport is and ask her if she can come to you, coffee encluded with the treatment. Warm, friendly, sympathetic to her being messed around and reasonable about what you can and can not do. You never know it might turn out that she lives around the corner and geting to you is no problem.
If she is the client from hell, it doesn't matter, you have not refused to perform the treatment, only changed the location, there for you have not broken any law. If the salon owner refuses to give you the phone number then again you have not done anything wrong and infact if this is the case then all you say is, Thats fine, then what day and time am I meeting the client at the salon?
Oh and I would keep the phone message, in the unlikely event that she contiues to snarl down the phone at you, its good to have the evidence of haresment. :hug:
