Alright, this time I expect the flaming so won't be as shocked as last time!
I was in a very busy Pret today with very limited sitting and half of the tables where occupied by people working on laptops or doing their coursework leaving no-where for others to sit!
I'm not saying it's never ok to occupy a table in a coffee place but surely people should use their common sense and move on if there are people standing and waiting to sit down?
