I'm not sure if the habit is because of the show or not, but I wanted to note for anyone who might be reading that "Detectorists" is a really charming British show that I highly recommend.
Yes, it was supposed to be a reference to the show, glad you picked up on it.
Pub?
Ohw hellow thayre! It’s a pretty good show indeed.
"Did you find gold?"
"Oh for fuck's sake".
Spring is coming up, the perfect time to re-watch Detectorists.
