BOSTON -- It couldn't have been easier. Donald Hayes, 54, said for months he would pull up to the drive-through at the Dunkin' Donuts on Middle Street and Route 53 in Weymouth and order a cup of coffee.

"Then, all of a sudden, they told me they won't serve me at the drive-up anymore," said Hayes, who is accusing the doughnut chain of discriminating against him because he is disabled.

Hayes said he has chronic-progressive multiple sclerosis and has used a wheelchair since 1994.

The Dunkin' Donuts Hayes frequented serves customers only at the drive-through. There is no restaurant with seating.

"They wanted me to go across Route 3 to a Shaws shopping plaza and use Dunkin' Donuts there," said Hayes.

"I couldn't even get the light to change because I couldn't reach the button (on the light pole at the intersection)," he said.

Andrew Mastrangelo, communications manager for Dunkin' Brands, Inc., refused to be interviewed on the Hayes situation. He sent the following statement:

"While Dunkin' Donuts does not have a corporate policy regarding the use of wheelchairs in our drive-throughs, our No. 1 priority is the safety of our customer. Our franchisee's objective in this particular instance is to protect customers from potential injury in a traffic accident."

Hayes, an ordained minister who does online ministry, said he is not asking for anything special. He said he has not contacted a lawyer.

"I am not looking for any monetary gains. I just want to get a cup of coffee," he said
