Some businesses might have a "tea break" or "coffee break" in the afternoon, sometime between lunchtime and closing time but there is no law saying this has to happen. In the UK, the employment laws state that all employees must have a break every 5 hours and that break only has to be 15 minutes in duration. I'm sure there are some companies, perhaps offices but not shops, where it's possible for everyone to stop work for 15 minutes in the afternoon but it's probably very rare. Most people who work from 9am to 5pm have a lunch break at about 12.30 to 1pm and that's it.
In my part-time job at a shop I start work at 8.45am, I have lunch from 12.45pm to 1.45pm and I finish work at 6.30pm. I do not get any other breaks.
