B: Yes?
A: What is this $18 charge for?
B: Oh, this is for the service fee.The charge goes to all of the 2nd floor customers.

B: I am sorry for the late notice.But only the 2nd floor is available now.
A: OK. And I saw the chicken is the special today, and it should be charged at $28, not $35.
B: Oh, yes, sorry for the mistake. Let me change it.
A: And the total should be $131, right?
