How may I help you today young man? It looks like you have a big package there.
Yes, ma'am, I need to mail this present to my grandma, but I don't know how to do it.
I can help you. Just go way it over there, it will print out the information on a piece of paper, that tells you the weight of the package, and the price to mail it, and you can bring it back to me.
Yes, ma'am, thank you so much.
