I went for my 2nd fitting yesterday and noticed what appeared to be a grease stain on the inside of my dress. I know that they did some alterations near that area, so I can only assume it is from their machine. I didn't say anything yesterday (since they had 4 people in the lobby waiting). I have to go back today... should I say something? The stain is on the inside of the dress, and not visible. My concern is that when they finish the rest of the alterations that it will happen again.
