For me, having a cup of coffee at "cafe" is to take a break alone or to talk with friends. But for these couples of weeks, I didn't have enough time to sip coffee with sitting down on the chair but on the counter.
In Japan, there are a lot of "vending machines" which sells coffees and other drinks. But here it isn't very common, but instead, they can have this "quick break" at the counter of cafe.
And there are some benefits 1)coffees are cheaper 2) sometimes, you can get to talk with other friendly customers.
