This always annoyed me in Gavin and Stacey, because I live about ten minutes from where the Shipman home is meant to be. Much like lots of the Essex contingent in the show I and many of my friends and family work in the city (some of the characters maybe do work locally in Billericay, but Gav and his dad are explicitly said to work in London and they talk about travelling in on the train etc). However, unlike Gav and Mick, I’ve ever sat down with my whole family before a work day for breakfast whilst reading a newspaper!
To get into the city for 9am- depending on where in the city and your proximity to a station this end- you’d have to be out of the door at 7.30am at the latest, so sitting down at about 6.45am for your bacon, egg and browse of the Daily Mail. No one does this; if you’re a breakfast eater it’s a quick bowl of cereal with one eye on BBC breakfast or you take your breakfast to work/have a coffee en route.
It’s also always full daylight in these scenes, even in parts of the story clearly set in the winter (and Pam is dressed and made up even though she doesn’t work and has no reason to be up about, cooking Mick and Gav a full English wearing lipstick and a proper bra, but that’s a whole other annoyance!)
There’s also several instances in the earlier episodes of Gav and Smithy meeting for lunch at a pub near where they live whilst Gav is on his lunch hour from work… it would take him longer than his lunch hour to get back to Billericay, never mind order, eat and get back. He’s on a four hour lunch break apparently! And don’t get me started on the black cab Gavin and Smithy take home from Leicester Square to Billericay in the very first episode… a 90minute drive in even light traffic which would probably cost you about £200 (at least!)
As you can see, I’ve thought about this all way too hard, but I didn’t know a single Essex local who didn't watch that show and take issue with all of the above. The only thing I can think is that for whatever reason they were set on the storyline being split between Barry and Essex, but only knew the logistics of the Barry half (Ruth Jones is from near enough to Barry I think, but James Cordon is from Uxbridge, west of London rather than east).
