One of my Pete Peeves; Splitting the Check.
Sure, we all go to lunch, and I get my half order because I really don't want the extra calories, and other people get a full order, oh and let me just add a side. Of course we need to cover for this guy because he's celebrating an event. Never mind the fact that I chipped in $25 for the gift for said event. So yeah, a $10 lunch cost me $25.
