Jeremy Clarkson has already lost a huge amount of money from new pub just days after it opened

Jeremy Clarkson has been talking more about the trials and tribulations of running a pub.

If you've not heard, he's finally found a way to get round the whole farm-restaurant thing by instead buying a pub and running it.

The Farmer's Dog opened to large crowds of punters, one of which has already managed to get themselves barred from the pub, while Clarkson has set himself a bit of a challenge.

He wants all of the food and drink served in his new pub to be British, which means there's no ketchup, coffee or Coca-Cola being served.

It's certainly a challenge, and while Clarkson's fame is bringing in plenty of customers, the financial challenges that many pub landlords face aren't lost on him either.

Writing in The Times, Clarkson admitted that all the people he'd 'pooh-poohed' over his attempts to go as British as possible may have had a point after all.

He explained that if he wanted to import a kilogram of black pepper that'd cost him about £10, but the domestically produced stuff would set him back 'ten times more'.

If he wanted to make sausages out of one of his own pigs then the cost of each sausage to him would be 74p, importing sausages from abroad would be worth just 18p each.

"It’s possible that for every customer who comes through the door I’d lose about £10," Clarkson wrote of his attempts to number-crunch the situation as he reckoned he'd need to charge about £45 for a fully British hot dog.

However, that's just the tip of the iceberg as the Clarkson's Farm lead wrote on that several other things about The Farmer's Dog had cost a veritable fortune.

It turned out that when you switched everything on inside the pub there wasn't enough electricity to power the extractor fan above the ovens, and when that goes down it also knocks off the gas supply too, rendering cooking impossible.

Some punters have been less than happy at the disruption to the kitchen and vowed never to return to the pub.

To fix this Clarkson was quoted £350,000, or at least that's the figure he wrote in his column that he said was 'the last number I heard, before I fainted'.

Other big costs to chuck on the pile included sorting out a supply of clean water, installing a defibrillator behind the bar and having to 'spend more thousands on a rolled-steel joist' to make his dreams of suspending a vintage tractor over the heads of pubgoers.

Clarkson has asked that if you're going to visit his pub to please remember that buying lunch is 'costing us a lot more than it’s costing you', so The Farmer's Dog team would appreciate your kindness about it.
