My Granddad once went to the doctor with a bad a cough and the doctor asked him why didn't he go to the pub next door and buy a double whiskey instead of bothering him with it!
But that doctor was one of the real old characters. There's a story which often got told years ago about when one of the local mechanics was called out to look at the doctor's car which wouldn't start, he fixed the problem and then charged him £20 for the repair. The doctor questioned the bill to which the mechanic replied to the doctor that the last time he had seen the doctor, he had walked in to the surgery, stated what was wrong, was given a prescription and had to go and buy the medication and the doctor charged £8 for the consultation. Whereas he had come out to see the car, spend time diagnosing the problem as the car wouldn't answer his questions, go and get a replacement part and come back and fit it so surely £20 was very good value for money compared to the doctor's charges
