i hate professors like that. FOr some reason, they dont realize I am paying for the class, and them locking the door, which i stand there and bang on until they let me in, creates more of a disruption than my walking in quietly 5 minutes late.
these also seem to be the same profs that believe their class is the only thing i have going on in my life, nevermind my 14 other credits and 30 hr/week work schedule.
