I would benefit from a 10 minute school lunch because i eat quickly and am usually throwing away my garbage and cleaning my area up 8 minutes into the start of my 30 minute lunch break but I have cold lunch and hot lunch kids usually wait 10+ minutes to get food and if they get their food at the same time lunch ends, Not good. . .
Many students need to wait in line for a school lunch. At my old middle school, We used to be called up by out table. For example, Monday would be table 1 goes up first, Then 2-5. Tuesday table 2-5 goes, Then table 1 last. Many of those kids waited 10-15 minutes just to start eating.
Also, Many students can not eat in 10 minutes. I would be completely finished in 10-15, But most students took longer. Also, Lunch is the time for us to talk and socialize.
Many students get their food from the school, So they have to queue for their food, Which could take a good 10 or 15 minutes. And, Some people are slow eaters. I know that I would take at least 15 minutes to eat. Also, I think that lunch time serves as a break to socialise with friends for many. It's good to break up the day, It maintains concentration.
My school has a 40 minute lunch and 30 minute interval. The bell goes 5 minutes before it ends and you only properly get to the lunch space 5 minutes into it. If you go to the bathroom, That takes 5 minutes. Queue up at the cafeteria, At least 10 minutes, At my school more. Eating is another 5-10 minutes. And students usually have a meeting or extracurricular in this time. And look, No time left to socialize or run around. How great is that? *They say sarcastically*
