There area a lot of edge cases with this scenario. In some fast food restaurants (such as certain Burger King locations), you will get a number and the employees will bring the food to you, so there is a minimal form of table service. Also, the history of the country matters as well. In China, where there is no tipping culture, but fast food started out as fancy expensive foreign food not too long ago, the employees are expected to clean up, even as prices are now lower relatively compared with moderately expensive restaurants. On the other hand, in Korea, where there also is no tipping culture, fast food is now cheaper food, and you clean up after yourself.
