Professor Hobo – college, students, professors, & cats

How true to life is this incident?  Ask any teacher.  Students always expect a teacher to know their name the first day of class, before they’ve even met you!  Of course, we all make presumptions similar to the one here.  I often walk out of stores with high priced electronics items and simply tell the clerk to put it on my tab.

They know my name by now, right?
