I need a job!Watch
You're less likely to get a job in the food industry because they usually involve selling stuff like alcohol and since you're underage that's illegal. If you do want a job in the hospitality industry then Levy UK could be a good option, look into hospitality agencies that offer zero-hour contracts, they often have jobs that don't require you to be over 18. Maybe put a focus on more retail jobs like primark, JD, H and M, or maybe a receptionist or even care work? The way I see things is, apply to whatever interests you, the worst they can say is no and the best outcome is you get the job.
