A、He had some drink at home. B、He had some drink at bar. C、He behaved rudely. D、He took a breathalyzer test. BWhat has Mr. Savag

W: If I understand you correctly, Mr. Savage, you were driving well within the speed limit when you were stopped by the Police.
M: That’s right. I always keep to the limit on Downside Road because there’s a school slap on the corner of the first turning and I wouldn’t want to run the risk of hitting one of the kids, now would I?
W: I’m afraid I do not know what you mean.
M: Well, I go by the speedometer, don’t I? That’s what a speedometer’s for, isn’t it, to tell you how fast you’re going. I mean a machine can’t lie, can it? People can, but not machines.
W: "Machines" as you call them are not necessarily in fallible(一贯正确的) guides, Mr. Savage. They sometimes go wrong. In any case according to the Police testimony you were driving at more than sixty miles an hour in such a manner as to cause a danger to the public. Weaving from side to side like a go-go dancer is what I think the Police Constable said.
M: Very funny, sir. Still, the steering wheel has been playing up a bit lately, I admit that. I said to my wife only the other day I’d better have it seen to, but she said she put if off till we went on holiday so...
W: Mr. Savage. Now,  I understand that when the Police stopped you, you refused to take a breathalyzer test... Why was that?
M: Well, I hadn’t been drinking, had I?  Half a lager and at the Feathers—you must be joking.
W:  It is not my habit to make jokes in court, Mr. Savage.
