I'm a big believer in please and thank you.
This morning I was trying to find a phone number, so I called 4-1-1. I really never use this service. But I needed to get a number faster than walking down the stairs, turning on the computer and looking anything up online. An automated voice came on the line asking for the name of business, city and state. I spoke my request. When the voice came back and asked "Do you want [blah blah blah...]?" I answered "yes, please." There was a pause on the line, and then it asked me the same question. I answered "yes, please," again. Automisses came back and asked me the same question for the third time. I think my face had a perplexed expression on it. Dubs laughed at me and said "Stop being so polite. You can't say please, just say yes."
I'm still a big believer in please and thank you. Except not when asking for phone numbers.
