If you go to London, consider sleeping in this coffee cup.

Founded in 1939, Greggs is now the largest chain of bakeries in the UK, specializing in sandwiches, Croissant, cakes, desserts and coffee. By 2012, Greggs had more than 1600 outlets, more than McDonald's in the UK.

Flat White, which originated in Australia, is also becoming a new product in coffee chains. Before Greggs, Starbucks, Costa and others also launched this kind of Flat White coffee. You can read about what this coffee is and how it became popular in the extended reading section at the end of the article. Of course, this is actually to promote Flat White Coffee, a new coffee recently launched by Greggs. "the British are coffee lovers," said Malcolm Copland, marketing director at Greggs. "on the one hand, we want to test whether a 20-minute sleep with a cup of coffee can make people more efficient, as the survey suggests, and on the other hand, we want to take this opportunity to give you a taste of something new." Sounds like fun. Greggs says his own research shows that sleeping for 20 minutes after drinking coffee can restore physical strength and improve productivity (are you sure you can fall asleep immediately after drinking coffee?). So they set up a bed in this big coffee cup so that pedestrians can go into the coffee cup and lie down after drinking Greggs coffee. If you go to London recently, you should be able to see a large overturned coffee cup on the grass in front of the Tower Bridge. This is actually an outdoor marketing run by Greggs, a London baking chain, on the streets of London, where passing guests are invited to have a cup of coffee in the large coffee cup called nappuccino and then lie down for a while.
