Well you kinda do... If he's done a good job (direct route, not taken the piss, been polite) then the custom is to round up the fare to the nearest £1.
Well, in restaurants now the tip's already on the bill, unless you want to make your entire group or date uncomfortable by "talking to the waiter about taking it off".
Really? I rarely have dinner over 20 pounds a person (which isn't cheap, I get it, but for London prices it's also not expensive), and I haven't seen a bill without service charge added in months (excluding Whetherspoons). As soon as I don't manage to order at the register, and instead someone brings a menu, there will be a service charge.
There was one restaurant recently that didn't have one, and we almost freaked out about it.
Not really, it's a service charge that in most places is charged for groups over a certain size (4 or 5). There is no culture of compulsory tipping for anything, because it's ridiculous.
My experience does not match what you are saying. I was always taught that (unless a service charge is already included) you should tip 10-20% in good restaurants. Not to tip I believe is generally seen as rude/a sign that service was bad.
Of course, most of us don't regularly eat in "good restaurants" - pretty much anything on the high street/your local shopping centre isn't, and anywhere you can get a meal for under £15 a head before drinks doesn't count as a "good restaurant", in my books.
I mean where you draw the line is up to you, but if there are three of you x £15, plus drinks lets say total of £64 , I would normally round it up to 70. By good restaurants I meant anything that isn't fast food (Subway, McDs). But perhaps I am not a typical customer, I don't know.
Often I go out to a restaurant with a friend and order fairly common food - totalling <£30 including drinks, and not making many demands of the staff. I don't think tipping someone to do the bare bones of their job is reasonable.
On the other hand, if I were to go with a reasonably sized group of people, had to get a table big enough for the lot of us, have people with dietary requirements or order cocktails or who otherwise make many demands of the staff... it's worth tipping as we're a pain in the ass, basically. And many restaurants automatically add a service charge in that case anyway.
