Some tips on booking:
When you are booking for another person, use your own name and email address and choose the service the other person wants. If they choose to book for themselves, they can use their own name and email address. The system won’t allow someone else’s name to be associated with your email. If you share an email address you can create the profile as “Bob and Lynn” for instance.
I also added a notes section to the appointment process, if you want to clarify any details about your visit.
