I have a customer who purchased some light fixtures from a local and reputable lighting supplier and the fixtures did not have any UL stickers on them and the way they had to be assembled was very questionable; I asked the manager of the store about the fixtures and was informed that they have been selling that brand of fixture for over 7 yrs and that they were fine;My question is.. should I have gone to the manager or should I go to the owner or just let it lie? (these folks do give me a fair amount of work)
