The other day a friend of mine and I went out to find a nice quiet restaurant where we could have breakfast and chat. We found one. There was nobody there except for a man reading a newspaper in the far edges of the outside dining area. We sat down, the waiter gave us the menus, and went inside. Next, this techno-pop music started playing. We really didn't want to listen to it, so I asked the waiter to turn it off.
He said no. He would not turn it off, but he would turn it down. If he turned it down, we couldn't tell. We sat there for a while and debated if we should stay or not, then decided to go and find another place. Thankfully they hadn't started cooking yet when I went inside and canceled our order. I explained that we really didn't want to listen to music. And we left.
I wonder if his boss told him "when there are customers, turn on the music." And the man had no instructions about what to do when the customer didn't want to listen to music!
