But what kind of impression does it give, especially in business?

Bad language has to be taken in context. Exchanging four-letter expletives while telling stories and jokes with friends in the pub is one thing. Directing foul and abusive language at people in anger is another.

But the middle ground - the grey area - of people you have just met or are doing business with, is far less clear cut.

When it comes to swearing, I am no saint . . . but I’m no outcast sinner, either.

I wouldn’t walk into a room with people I had just met and start letting rip with the f-word, among others, as we talk about everything from the weather to my journey to the meeting. To me, that shows a level of disrespect.

Equally, people who have been talking to me who may have have started with s… or f… but sidestepped with a shoot or flip. I noted their restraint and appreciated their respect and professionalism.

If you don’t know how people will react, don’t take a chance.

Even with people I know well, bad language can come across as unprofessional.

Some people can’t seem to help themselves and use swear words like other people use (or misuse) commas.

I was recently at a meeting with bosses from a variety of industries and was shocked when a female director began to describe some of the issues her company faced with language more suited to the football terraces.

I think my facial expressions hid my true feelings and everyone else in the room either displayed the same self-control – or they really weren't bothered by it. The fact that no one else joined in with the swearing carnival makes me think it was the former.

She was clearly very good at what she did and knew her industry inside out. But with each additional four-letter offering – and she got through most of them – I found it difficult to take her seriously. I wasn’t even interested in engaging in conversation with her.

It put me off her - and her company. 

But is swearing any worse or better than someone turning up for a high-level meeting in ripped jeans and a T-shirt instead of a suit? 

Am I being too sensitive?
