Is it taboo to get a tattoo from a different artist in the same shop?

I got a thigh piece done by a great artist in September 2015 and now I am wanting to get another one on my ribs from the same shop. I really like this other tattoo artist who works in the same shop and wanted to get a piece done by them as well. I don’t want to piss off my old artist though since I am wanting to go back for a different piece later on.

My old artist may not even remember me but I don’t wanna be a dick, so if anyone could help me out that would be great. I just really love both their work for different reasons.
