How do i word my previous job responsibilities in a professional manner?

[Lyss]

I'm applying as a CNA for a hospital, the other jobs that i've previously held include, bartender, waitress and barista... i was wondering if there's a more professional way of putting my job responsibilities of: Customer service, punctuality, responsibility, bartending, waitressing, cooking, cleaning, serving food, operating cash register, stocking.

any suggestions would be MUCH appreciated, THANK YOU!
