Joelle, Dan and Brian enjoy conference calls.
Joelle, Dan and Brian order new cell phones : one from Bell, another from Sprint and one from AT&T.
All three go to the Conference Call Centre to pick up their cell phones.

"Who ordered what?" asks the man at the counter.
Dan says, "I didn't order from AT&T."
The guy who ordered from Sprint says: "Oh, I thought you did."
That was all the man at the counter needed to know.
