From a store clerk:
"The computerized cash register is down. I'll just add up your purchases with a pencil and paper."
"I'll take a break after I finish waiting on these customers."
"We're sorry we sold you defective merchandise. We'll pick it up at your home and bring you a new one or give you a complete refund, whichever you prefer."
From a contractor:
"Whoever worked on this before sure knew what he was doing."
"I think I came in a little high on that estimate."
From a restaurant server:
"I think it's presumptuous for a waiter to volunteer his name, but since you ask, it's Tim."
"I was slow and inattentive. I cannot accept any tip."
