Most useless business phrases

I'm not sure if Blogger supports polling, but if I could construct a poll, I'd ask you which of these phrases is the most useless business phrase.

1. Have a nice day.
2. We value you as a customer.
3. Your call is very important to us.

Personally, I lean toward number 3, since I only hear this phrase when a company is busy and doesn't want to talk to me.
