Hi Lev,
I have seen cases like this before where Google automatically appends your business name to the Meta Tile Tag you have specified. From my experience, this is only done by Google when there is enough space to do so without impacting the Title Tag you have written for the page.
So if there is blank space available at the end, Google may append your business name to the title.If you have specified a Title Tag that does not leave Google enough space to append the business name, they will not include it.
So in your example, feel free to write Title Tags that make use of all the available space.
P.S. Google limits title tags by width (600 pixels), not characters.
