Do I call the installer back for one dented tile? [View all]

I went through a designer, because I couldn't figure out what sort of backsplash I wanted for the kitchen, and she helped me pick a very nice brushed aluminum (I assume? It's metal attached to ceramic) subway tile. When I arrived home, everything looked great except for one, possibly two, things.

The first is that one of the tiles has a small dent. I don't know if I should call and ask for it to be replaced or if that's going to cause a whole lot of problems. It's not as if it's in a very visible place, but I'm sure the installer saw it and ignored it. I know if it was a cracked tile, I'd want it to be replaced, but am I being too picky, or wanting things I pay for to be finished right.

The other is that they didn't start the tile where I thought they should. I thought they'd line it up with the upper cabinet, but they lined it up about 1" to the left, at the end of the granite. Is that usual?

Thanks in advance for any advice.
