“The manual” when paying for a service

Hi Brooke! I’m learning so much this month and doing pretty well at letting go of the manual with my nearest and dearest. My question: -Is it appropriate to have a manual when we’ve paid for someone to provide a service? I’ve noticed I experience a lot of frustration and disappointment when I’ve paid for a service and I don’t think it’s been delivered adequately or the service is unprofessional. I can see it’s not helpful for me to get so upset and frustrated – but at the same time I believe it must be appropriate to hold someone to a standard for paid work. Does it makes sense to have a manual in this context – or is this a situation where boundaries are appropriate? Thank you!!
