If you just need a pivot-table layout, you can get it like this. Note that the formula is an array formula, entered with CTRL+SHIFT+ENTER. Then just drag the formula down to the Service2 and Service3 cells.
Someone smarter than me may come up with it; but I've been unable to use "MODE" in a pivot table calculated field. I suspect it's because you'd have to involve an array of values in the pivot table calculated field -- which may not be supported.
