You might have noticed before, or not noticed but still seen, the company name variations that some anime have to avoid copyright infringement. Feel free to post any that you find, and if possible, where you found it. Also, a picture would be nice. 
An example I have ready:
Kenta Chicken Fried (KCF) from Kentuky Fried Chicken, which I found in Higurashi no Naku Koro ni.
WacDonalds pops up a lot. I've also seen Starducks, but I'm not sure where.
I want to say it was in the Negima! manga, that there is a cafe by the name of Starbooks.
And Kentakun ftw!
