In the UK, we generally tip for a great service. If I buy a meal and the food and service is just fine, then no tip. Though if the food and service are great, I will generally tip 10 - 20% depending on how generous I'm feeling at the time. Tips generally aren't expected, and you won't be shamed if you don't tip. I would clean up after myself somewhere like McDonalds or Burger King, though in a cafe or restaurant I wouldn't. In a restaurant I usually put the plates together to make it easier for the waiter or waitress to clear the table and try not to be too messy.
