Chanel bosses stopped its perfume being sold from an Aberdeen shop due to the state of Union Street.
The luxury French brand axed its account with Michies Pharmacy partly because the quality of the surrounding businesses wasn't up to its usual standards.
Rosemary Michie, public relations manager at Michies, said it was a "significant blow" when the major account was closed.
The businesswoman was commenting as debate continues on the decline of Aberdeen city centre.
The Press & Journal says it comes after Jamieson and Carry launched unsuccessful efforts to prevent a takeaway opening next door on Union Street.
The jeweller argued it would bring down the area at a time when it's ploughing £1million into a pair of neighbouring vacant units.
Concerns
While some accused the Aberdeen institution of "snobbery", others backed the stance amid concerns about a saturation of fast food outlets.
Ms Michie shared her own experience to highlight the struggles local traders are facing.
In a LinkedIn post, she said her firm "supports Jamieson and Carry on this one".
She added: "We have personal experience with this type of issue.
"Chanel Fragrances closed our account at Michies Pharmacy years ago - citing one of the reasons as being that the category of surrounding businesses didn't meet their brand criteria.
"It was a major account for us, and a significant blow to our retail offering."
Future applications
Though the takeaway proposal has now been rubber-stamped, Ms Michie is hopeful the council takes her message on board in deciding future applications.
Michies dates back to 1921 and its main branch is the three-storey building at the top of the Granite Mile.
The claims about Chanel reinforce concerns raised by Jamieson and Carry about the takeaway opening next door.
Bosses voiced fears that luxury Swiss watchmaker Tag Heuer would axe an agreement with the Aberdeen firm if its products were being sold next to the fast-food business.
They said "brand representatives" often inspect surrounding areas to ensure they "are commensurate with the high standards associated with the watches themselves".
Our Union Street campaign
Ms Michie's comments comes as the Our Union Street campaign picks up steam.
More than 4,350 ideas to help breathe new life into the heart of Aberdeen have been suggested by the public.
Bob Keiller, chairman of the recently-formed Our Union Street group, has described the response as "remarkable" and thanked all those who want to be part of the conversation about the future of Aberdeen city centre.
The group has published all of the ideas, unfiltered, on its website ahead of a planned public meeting expected to be announced in the coming weeks.
Mr Keiller said he wants everyone to be able to access the ideas put forward and has published them all online.
Our Union Street was a product of November's emergency Union Street summit.
The organisation has been set-up by Aberdeen & Grampian Chamber of Commerce, Aberdeen Inspired, Aberdeen City Council and Opportunity North East, with additional support from Shell, which recently relocated to the street.
