Keen congregation secretaries are a pain. I know I was one.
They typically remind you when your blood card is out of date (5 years in the UK). They get reminders to remind the congo and so occasional announcements about "only e.g. 70% of you have up to date blood cards on file, what would you do if you were in an accident etc.")
That's as far as I went, but more recent secretaries in my congo go further.
Some secretaries remind you personally or by text. I had a reminder last year by text. I texted back "thanks for the reminder, Mike" and heard nothing since.
if pushed further I am resolved to say "thank you for the reminder" and I will SHUT UP. Whatever is said then will be met with "like I said, thanks for the reminder".
Sec'y: "Blah blah accident blah blah for your protection blah"
Freddo: "Like I said twice already, thanks for the reminder."
Sec'y: "Aren't you going to fill out a card then Freddo?"
Freddo: "Like I said three times already, thanks for the reminder."
Sec'y: "Sounds like your stalling me Freddo."
Freddo: "Like I said four times already, thanks for the reminder."
Sec'y: Eventually runs out of steam.
