Помогите, пожалуйста!Read about the problem. Fast Food Restaurants have become very

As for me, I support the idea that the service is very quick in Fast Food Restaurants. 
As it comes from the name of the restaurant, you go there to get a quick snack.
If you don't have much time or don't want to wait you go there and get a sandwich or something like that so as not to feel hungry any more. So, some more "for" are as follows:
-The food is rather cheap
-The people working there are usually young and friendly
-The food is usually fresh
Of course everyone chooses his or her Fast Food restaurant but the chains they have usually offer the same dishes all over the world.

I personally support the idea that "Fast Food restaurants are the same everywhere, so you know exactly what you want". Fast food chains like McDonald's and KFC tend to have the same menu everywhere in the world with the exception of some items that are specific to certain countries. Therefore, even if you go abroad and want to grab a quick meal, you know exactly what to order even if you can't speak the language.

Here are some more arguments to support the idea of Fast Food Restaurants:
-The food is affordable and better than snacks. Quite often many teenagers can be seen in fast food restaurants on the weekends because they can't afford to have food at sit-down restaurant when they get hungry. So instead they tend to buy sugary and unhealthy snacks like crisps and chocolate bars. Although fast foods are not as healthy as home-made food, they are still more nutritious and filling that snack that are full of empty calories.
- They are convenient. There is usually a large number of fast food places near business districts so it makes it easier for busy office and shop workers with short breaks to grab a quick lunch or even have it delivered to their workplace. 
- Takeaway food. Sometime families don't feel like cooking food for dinner so they can always order a large family-size meal instead. There are even healthy options like salads. 
- Job opportunity. Fast Food Restaurants offer jobs to thousands of people worldwide especially to students who struggle to support themselves while studying at the university.
