Questions 21-25
I got used, too. To my employer’s violent changes of front. There was one morning when Siegfried came down to breakfast, rubbing a hand wearily over red-rimmed eyes.
‘Out at 2 a.m.,’ he groaned, buttering his toast listlessly. ‘And I don’t like to have to say this, James, but it’s all your fault.’
‘My fault?’ I said, startled.
‘Yes lad, your fault. The farmer has a sick cow for several days and at 2 o’clock this morning he finally decided to call the vet. When I pointed out it could have waited a few hours more he said Mr. Herriot told him never to hesitate to ring—he’d come out any hour of the day or night.’
He tapped the top of his egg as though the effort was almost too much for him. ‘Well, it’s all very well being conscientious and all that, but if a thing has waited several days it can wait till morning. You’re spoiling these chaps, James, and I’m getting the backwash of it. I’m sick and tired of being dragged out of bed for trifles.’
‘I’m truly sorry, Siegfried. I honestly had no wish to do that to you. Maybe it’s just my inexperience. If I didn’t go out, I’d be worried the animal might die. If I left it till morning and it died, how would I feel?’
‘That’s all right,’ snapped Siegfried. ‘There’s nothing like a dead animal to bring them to their senses. They’ll call us out a bit earlier next time.’
I absorbed this bit of advice and tried to act on it. A week later, Siegfried said he wanted a word with me.
‘James, I know you won’t mind my saying this, but old Sumner was complaining to me today. He says he rang you the other night and you refused to come out to his cow. He’s a good client, you know, and a very nice fellow, but he was quite shirty about it. We don’t want to lose a chap like that.’
