Agree with the above.
You may also want to consider the following:-
As
@threeportdrift has said, most employers want to see some evidence that you've got a natural passion for the type of job you're applying for. For example, you mention that you like Chess... although this will impress those who are looking for someone with meticulous, methodical, analytical, strategic or problem solving skills, it's not really relevant for catering or retail positions, and certainly not for the entry level positions you're presumably applying for. Also, it's a different kind of pressure you'll get from working in retail / fast food. They'll want an example of pressure from working in a busy, fast paced environment with demanding customers / clients.
As you mentioned fast food, could you not include something like you enjoy hosting and cooking for your friends? Do you have an online blog regarding cooking catering etc? You could say you really enjoyed the team exercises in school / college as there's a real sense of camaraderie (employers love that sort of stuff)... especially when you've smashed it by getting a good grade.
Please try and make sure your CV fills the entire page, without it being too "
wordy" (should be either exactly one or two sides of A4) Bullet points are good as it makes the information easy to find. I would also suggest swapping the order of your grades so your predicted "A" level grades come first. You've included GCSE Maths and English language, which is good... but it may also be worth including any subjects you studied that are relevant to this (e.g. home economics, marketing, anything hygiene related etc.)
