A rant about cafe/coffee bars in the UK

What is wrong with the Brits? please don't all shout at once out there, because I could spend the next half dozen posts telling you things which you may not have thought of as wrong with the Brits & our culture.
However there is one thing that really pisses me off BIG time.
Its this: I love my coffee, I love it black & strong, I like it at home & I especially love to linger in a cafe chatting with a mate or watching the world pass by.
But this is how it goes in the UK: You go into the cafe/coffee bar & have to queue up to order you drink at the counter, You stand there & carry it over to your table yourself & then the Cheeky bastards expect a tip or else there is a large cup placed nearby  the cash register for the customer to put a tip in!!
Now tell me-what am I giving a tip for??  Its not for the privilege of being served at the table!
On the continent you sit down in a bar, cafe,or coffee bar & the waiter comes to you in moments to take your order & then returns with your coffee, whatever in a short while. But here in the UK its as if its a chore for the staff to serve you & that we (the customer ) should be damn grateful to be served at all.
Its happen twice to me in the last couple of days. I have incidentally tried just sitting down & waited for a member of the staff to come & serve me but only to be ignored.
Yesterday Kate & her friend Sharon were in a local cafe. They had two coffees, & Sharon ordered & ate brunch. They then sat there for some 45mins chatting. Then as lunch time drew near the waitress came over & asked them to vacate the table as they needed it for the lunchtime!  WTF!! I'm sorry but I think I would have made a scene of this kind of very poor customer service. I've had enough of being taken for a prat.
