I don't know if anyone mentioned it, but it's best not to include "hobbies" or "interests" because it allows for the screener to be biased. You have to keep it as professional and to the point as possible, particularly pertaining to the job you are applying for. If you write something like skating or soccer for interests, well that isn't really relevant to most jobs, it's useless.
Only include things that boosts your chances of being screened in and considered which are relevant. The best way to do it is to look at the job posting and look at what they require, then tweak your CV to include those "keywords/phrases" so if it is an electronic screening system, then it will catch the keywords and screen you in.
In job postings there are two main sections to focus on: Employee duties/responsibilities (which is the work that is required of you to perform) and Qualifications/Required skills/credentials (which are the minimum skills, competencies, and experiences you need to pass initial screening). Your resume and cover letter should clearly indicate you have met their minimum criteria, and its important to throw in those catchy keywords/phrases from the "responsibilities" section because sometimes having those are considered assets.
For retail like you said, you don't need it, but keep these things in mind for the future when you are applying to other places inshallah.
