During the week, people use pubs for a quick lunchtime drink or a social meeting, while on weekends, you will find families in pubs as well as groups of friends.It’s unusual for someone to buy only their own drinks in a pub or bar. Speaking of bar, it opens at night, while pubs open in the afternoon, evening and night, which is more influential in UK while bar is more common in US. 
Oh, forget to tell you! You cannot walk into a British pub and ask for a beer—it’s a bit like saying “I want something to drink.” The Barman will just look at you and wait for you to say what you want.
we really enjoyed a lot at pubs
