Since you've added several specific brands already, how about:
McDonalds, Chic-fil-A, Wendy's, Burger King, Sonic, etc.
Convenience Store or Quick-Mart
Friend, Family, Meeting (I'm not sure what they would look like, but it would be nice to distinguish, quantify and summarize time spend at these categories of places)
On a lighter note...
Just on principle, shouldn't the Gas Station icon be removed! Or at least changed to "Service Station" with a different icon like a mechanic? If anyone is going to gas pumps, they shouldn't be here, right? ;-)
