Diner Envy.

What is it about human nature that invokes such a strong emotion as jealousy? To be envious for no apparent reason - to someone you don't even know or have never met before - seems odd to me. That kind of negative thinking is either built within you from birth, or takes several years of mistrust and bad influence to grow and fester. Like someone seeing a glass as half empty rather than the other way around.

Last night my wife and I, went for dinner to a favourite restaurant haunt of ours. We know the staff well enough to call ourselves regulars. We are creatures of habit, and normally go for the same dinner and drinks every time. The food is excellent and the service is very good. We always sit at the bar for quick service and to chat to the staff - who are always friendly.

Along the bar, the turnover of people coming and going in this establishment, is high. People come in on their own, have one drink and a bite to eat and are gone within 30 minutes. Others have a drink at the bar, whilst waiting for their tables to be vacated by other diners. It's a hive of activity - and a great place to people watch.

But sometimes you don't have to look too far to spot a negative character. Body language can give it away - long before a word is uttered. And when this body language displays all the characteristics of one of the seven deadly sins, everyone starts to walk a little more gingerly around such negativity.

Over my right shoulder last night, I could sense the begrudgery as he sat down. He took an age to take off his long black coat, scarf and gloves and drape them over his high stool. He almost knocked over three plates a server was delivering to a nearby table, as he swooshed his coat off. He tutted as the server finally got by.

His stool was more than two feet away from mine, yet he still managed to brush off me as his bottom made contact with the leather cushion of the stool. And he wasn't a big man. No apology was forthcoming, and this gave me an indication of what kind of character was now sitting beside us. My wife copped it too, yet we said nothing. We see these people on a regular basis.

His bar server was quick to meet and greet him, yet she got little more than a grunt from him. Muted one word answers were his norm. His shoulders sagged and his elbows propped him up on the bar counter. Bad manners and posture afflicted him too.

His server found it difficult to understand him from less than five feet away. Irritation entered his voice at repeating his order of "Bloody Mary" - which sounded more like "Blah Mar". We determined quickly enough that he wasn't a man who depended on his communication skills to get by in life.

While we waited for our food, we chatted with two of the servers behind the bar. They had time to do their jobs and still be courteous and polite to everyone.

Then we felt a stare. Like we were monopolising the servers with our chat. For a man that could barely communicate seconds earlier, he was now eager to order his food.

He had spent about five minutes reading the menu and ignoring the servers. As soon as they were interacting with us, he wanted attention. He struck me as a man who was used to others waiting on him. He was impatient and regularly interrupted others. God forbid he had to wait.

Then came the bitchy, snide comment. Our server asked if he was now ready to order. Two of them has asked him at least once each, if he was ready. He never had the decency to even look up as someone spoke to him.

"While you two were too busy talking, your other colleague took my order."

Our server, well experienced and quick as a flash - put him back in his place.

"Oh really sir? What did you order?"

"Prawns and bisque."

"Great choice! The prawns are excellent. How is your Bloody Mary? Would you like another?"

This time she got half a smile. She didn't even acknowledge his attitude and rose above his level of negativity - this seemed to bring slight appreciation from him. He had baited her with a put down, but she spotted it and complimented him back.

He was looking for a snarly response but she was far more professional than he would ever be. He slurped his soup and left shortly after. No one was entertaining him. Everyone along the bar appreciated his departure. Even the faces of the servers looked relieved. His disposition was draining.

The man was envious of people having a bright and positive personality - something he never obviously possessed.
