That's very interesting. (Pre-Corona) I used to spend a lot of days working in coffee shops all around the city. Never at all felt any time pressure, whether in a small independent shop or a Starbucks/Costa type place. That's helped of course by the better shops making good food, too.
Which city are you in? I suspect the time pressure might be of a different magnitude in a city with a denser population, where the rent per sq ft might also be significantly higher.
