Everybody has at least one.
That's the motto for mypetpeeves.com, a Web site solely dedicated for people to post their own pet peeves.
Whether it's people chewing with their mouths open, unsolicited phone calls or spam e-mail, pet peeves are everywhere.
According to the Bureau of Labor Statistics, people worked an average of 7.5 hours a day in 2005. They worked longer hours on weekdays (7.9 hours) compared to weekend days (5.5 hours).
With Americans spending nearly half of their days at the workplace, the list of pet peeves are endless.
Ted Wybensinger of Sandusky has a lot of experience waiting on customers. After working in the restaurant business for more than a decade, Wybensinger has a list full of pet peeves.
"Nobody else wants to hear your conversations," said Wybensinger about people who talk on their cell phones -- specifically the walkie-talkie types -- at the dinner table.
Another thing that perturbs Wybensinger is tips.
"It's not 10 percent," he said about the amount that he has received from customers.
"Today's day and age, it's 18-20 percent depending on your server. Customers don't understand how hard it can be to get (orders) out."
Rude people also makes his list of annoyances at work.
Grocery store customer service
"My worst pet peeve is irresponsibility," said Kroger's service director, Annette Riesterer.
When employees call in sick or can't make it to work, Riesterer said other employees should help out with the extra workload. Co-workers who are "not stepping up and being a team player," is her No. 1 complaint.
Riesterer, who has worked for the company more than 30 years, said she enjoys working with customers on a daily basis. Over the years, she has learned many of the customers' first names, making the friendly customer-employee relationships her favorite part of the job.
"We try to make (customers) feel comfortable," she said. "Customer service is very important to us and we want our customers to feel welcome and comfortable inside the store."
But talking to people every day can also have its downside.
"I think we do a good job and some people don't seem to appreciate the job that we do," she said. "We always go out of our way."
Dave Griffith has worked for the U.S. Postal Service for more than 25 years. He describes himself as a person who "rolls with the punches."
Griffith, a postmaster, usually arrives at work around 7:30 a.m.
He enjoys helping customers and celebrating the successes his crew accomplishes -- most recently an employee who saved a customer's life.
But there is one thing that irks him about work.
"They hit me up as soon as I get in the door," Griffith said about his fellow employees.
"I like to get in, and unload my stuff, check the floor and then see what they need."
Griffith, who manages the day-to-day operations at the post office on 2220 Caldwell St., would like to get into the building and "get all my ducks in order," before the questions begin.
Other than that, Griffith said nothing else at work really perturbs him.
"I'm too busy to have many (pet peeves)."
Vern Blake is the general manager of the Mickey Mart gas station on Washington Street.
His top complaint?
"Workers who don't pay attention to customers," he said.
Blake enjoys helping out customers -- whether it's pumping gas for elders, or giving directions to lost folks.
Visiting other gas stations, Blake said he normally doesn't encounter employees who don't pay attention to the customers.
"You usually don't get that at other places," he said.
But the list doesn't end there.
Promptness, neatness and workers' appearances also make his list of pet peeves.
