I did the same as you (for work experience) I'd love to know also haha

You could say: you improved your interaction skills with customers which allowed you to provide better customer service; you were flexible and efficient on the shop floor which allowed you to cater to different customer needs without delay; giving helpful solutions to queries etc; as well as providing an enthusiastic hands-on approach, you are skilled and practiced in creating and formatting invoices or something like that.

Hope this helps
