It is and you shouldn’t agree to it.
I had one CFI candidate put with a by the FSDO assigned DPE and my candidate had to fly the examiner to another Airport, wait three hours for him to complete a Private checkride and then fly him back.
He later had his DPE-ness revoked by the FSDO.
There are a-holes out there looking to make a buck.
And unless you file a complaint with the FAA they’ll never do anything about it.
Anyways, enough of that.
Congratulations on passing what’s no doubt one of the mile stones in your career.
Certain check rides are life altering and this is one of them.
