This is how the gay activism agenda works:
A gay activist sets up the situation by choosing a Christian provider.
They have someone else who doesn't look or sound gay to call and engage the service. In this case, the guy's sister called.
Everything seems fine, so the provider accepts.
After awhile, the gay person(s) reveal their preferences for a gay theme.
The Christian provider must then either honor the appointment or turn it down.
If the provider cancels the appointment and cites his/her Christianity, the gay person calls the nearest socialist democrat lawyer or Human Rights Commission (they have them on speed dial) and the persecution moves into high gear.

It's a shake-down formula.
