can someone help with my resume?

For a finance class im supposed to write a resume. They want me to describe my potitons held in a business way as possible.Here is an example:

Hostess:

-Implemented online check-in process to decrease patron wait times by 50%
-Created online billing process and reduced nonpayment of services by 25%
-Explained seasonal menu items and daily specials to prospective customers

My position are Sushi Chief assistant, Cashier, and Grill cook. I have a few,but would like to put more. Any ideas. I am sorry for putting it in the wrong topic. not sure where i could have.

Cashier – I once saw an example online that said something like “Routinely managed monetary transactions of up to $XX.” Wasn’t useful for me as my job gets all kinds of different transactions and totals, but maybe that would work for you?

Other ideas:
Handled customer complaints
Completed transactions quickly and accurately (my store has an items-per-hour number, does yours?)
Managed various types of transactions, such as money orders, bill payments, credit card applications, etc (depending on what you have or have not done)

Search online for three separate searches – “resume grill cook” and “resume sushi chef” and “resume cashier” – and you will have plenty of sample resumes to look at for ideas.

Thanks , this really helped out a lot.
