I was watching Die Hard. John McClane had rushed to the roof of a building, and he was trying to talk to the police to ask for help by using some kind of radio signal, but his act was misunderstood to be a prank. He was angry and shouted at the policewoman on the radio. Here is what he said to the policewoman:
"Do I sound like I am ordering a pizza?"
I am wondering why it was not,
Does it sound like I am ordering a pizza
Do the two sentences make any difference in meaning?
