ALLENTOWN, Pa. (AP) _ For Wawa foodstores, one slightly silly-sounding name in the business is enough.

The Wawa chain, with 500 outlets in five states, is demanding in a federal lawsuit that the lone HAHA market, in Seipstown, change its name.

U.S. District Judge Edward Cahn tried to bring the two sides to an amicable agreement Tuesday. Unable to do so, Cahn scheduled a preliminary injunction hearing in the trademark dispute for July 12.

HAHA owners Tamilee and George Haaf II said they have a perfect right to the name, since it is an abbreviation of their own surname. Rather than call the shop Haaf and Haaf when they opened in December, they chopped the first letters off and combined them.

Wawa claimed in court papers filed last month that HAHA is deceiving the public into believing it has a Wawa connection.

Wawa was named after the town of Wawa, outside Philadelphia, and is the Lenni Lenape word for goose _ the company logo.
