Waiter: [o.s] Room service.
Lilith: Go away!
Waiter: [o.s] But I've got your ketchup, ma'am.
Lilith: Not necessary.
Waiter: [o.s] Okay, but I need the bill.
Lilith: Later.
Frasier: Well, let's just take care of this... [Frasier opens the door]
Waiter: I'm sorry to disturb you, but here's the... [noticing it's a different man] ketchup. Sorry it took so... long. I, er, still need the bill. Where's the cart?
Lilith: In the bathroom.
Frasier: Why is the breakfast cart in the bathroom?
Lilith: Uh. I was going to take a hot bath while I ate.
Frasier: Still, food in the bathroom?
