Carryout Tips?

[WLVRYN]

The NYC tipping question got me thinking about something that I struggle with sometimes (we have two little ones at home, we get carryout a fair amount). What's the appropriate amount to tip for a carryout order? If I'm getting it and work is paying (late night at the office or something), I generally tip 20%. If its on my own dime, I'm usually a little less generous (10-15%).

Any thoughts?
