Jobs for 16 year olds?

Currently working at a restaurant around the corner for a low pay and hardly an hours. I probably get around £16 a month. The people there aren’t the nicest either. I’m just wondering what other options are available? I’m put off being a waitress completely due to the rude customers and such, so what other jobs are available at my age? Please comment below any suggestions as I’d love to be able to quit my job as soon as I can🙄
