A spokesman for Franklin says the situation unfolded Tuesday at a Johnny Rockets restaurant on the Canadian side of Niagara Falls.
The spokesman said Franklin ordered a hamburger after performing a sold-out show, but the server screamed at Franklin, saying she couldn't sit down to eat because she had ordered takeout.
In a statement Franklin calledthe restaurant worker was "very rude, unprofessional and nasty."
A Johnny Rockets spokeswoman says the franchise owner is sorry for the actions of "a new and very young employee." She said the owner has spoken with the employee and has clarified his takeout policies.
