I wouldn't have ANY problem letting her know whats what.
YOU are not being paid to care one whit how she feels,what she likes,how she wants things to be
SHE IS being paid to care how you feel,what you want, and what you like.
It is YOUR house and you can be just as cranky,demanding,bitty as you like thats your right and YOU are the customer!
She is not doing you a favor. She is being paid. She is also a dime a dozen. If she doesn't want to do as you say, then she can hit the road! I don't care if your writing the check or if it's paid on your behafe. You are the boss, if she doesn't defer to you, she needs to go.I can understand telling her once. but only once.
I say demand your right to customer service! Demand your wishes be met! Proclaim it is your home and your rules and what you say goes!
If the company doesnt want to cater to your needs there is always another one willing to.
I guess I am the grumpy one
I am sorry, I wont tolerate any defiance from some twit in my own home.
