I don't think I'm going to help a customer to talk with manager.
Why don't you want to help a customer?
This customer made a stupid joke to me so I don't take him seriously.
Not all customers are easy to get along with but it is your job. It is important to keep customers happy so they will come back to the business.
Idk, maybe this customer isn't worth my time.
I'm sure your boss would say otherwise. You ought to always work hard to keep customer's happy.
