The pub lunch is the thing I miss most about my first job.
Every Friday almost the entire office would decamp down to a local pub for lunch and a pint or two.
The quality of the food was always very hit-or-miss (unless we went down the king's arms*, but that was seen as a bit pricey and fancy), and for many places if there were too many of us would get arsey for not booking ahead.
But it was a great opportunity to just hear what everyone was up to and have a good chat in an unstructured way.
I don't know if it's changing attitudes over the past 20 years, the particular companies I found myself at, the price of going to the pub, but it hasn't really been a thing at any of my places since.
Now with WFH of course there is a complete absence of unstructured conversation. Every meeting has a purpose, every interaction there's something someone has in mind they want from the conversation.
And while it's not impossible to chit chat still, it is impossible to overhear chit-chat, which is an underappreciated thing.
Overheard conversations are a gold mine of knowledge sharing, many an interesting idea has come about because, "I couldn't help but overhear...".
Now don't get me wrong, I don't want to suffer an hour long commute for that benefit, the cost-benefit skews all wrong. But I would like if everyone lived a 5 minute walk from the office.
