A tempest in a Tim Hortons decaf cup is brewing in New Brunswick.

Jimmy Craig said Monday he's been banned from two Tim Hortons outlets in the province because of his complaints about the decaf, but the company said it made the decision after he became aggressive with staff.

Craig said he voiced his displeasure on several occasions over the last two years about "burnt" decaffeinated coffee at a Tim Hortons in St. Andrews.

"I made a complaint to the store manager in 2008 and things changed for a while and the coffee got better and then, in 2009, it went back to the same thing - getting burnt coffee all of the time," he said.

"There comes a point when you get tired of going back to the store to get it replaced. And it adds up when you drink three or four a day to throw almost $2 coffee away."

Craig said he filed two complaints with the company's corporate office, then met with the store manager who informed him he is now banned for life from that outlet and another one in nearby St. Stephen.

In a statement, company spokesman David Morelli said no matter what staff at the St. Andrews store did to address Craig's complaints, he was unhappy.

"He became increasingly aggressive with store staff and was impacting their ability to serve other customers," Morelli said. "Our staff work long and hard to please each customer every day, but at some point we have to respectfully agree to disagree."

But Craig, who works as a paramedic, said he was always polite and never became aggressive.

"I wasn't going in and ranting and raving," he said. "I was going back in and saying the coffee was burnt and asking for another one, and they gave me another one."

Craig said he will talk to a lawyer to see what can be done to get the ban lifted. He said the ban impacts on his second job.

"I also work for a transportation company in St. Andrews and if I have a busload of 20 people that want to stop in and get a coffee, I should be allowed in the parking lot to let them get a coffee. As it stands now, I can't."

Craig said he hasn't had any issue with the coffee from other Tim Hortons outlets, but he'll be making his coffee at home from now on.
