No-Shows...
One thing I hate about tutoring, is when the kids no-show. I went to Tim Hortons at the appropriate time, bought my coffee, and waited. And waited, and waited. After a quarter of an hour later, I left.
I don't mind if people call ahead of time and cancel, but it annoys me when I drive to meet them, and they don't show. It's a waste of my time, especially when I could be studying for final exams. I guess I shouldn't be too mad, since they'll have to pay anyway. That way no-shows are minimized, but not tonight...
