You're always in control. You always choose what support and services you'll offer.
If you're not able to, or not comfortable with, providing something, let the Member know you're not the right person or not qualified or experienced in what they seek.
You might not wish to offer a service due to:
* You're not qualified or trained for the task
* Personal beliefs, religious or other reasons
* You feel unsafe / uncomfortable with tasks
* It's illegal, unprofessional or inappropriate
You can ask a Member if they're willing to train you or pay for extra training.
It's important to remember... you're a professional and also you're in control!
