So I am nutso about being on time, never tardy!  I consider it a great character flaw!
Same! At least 10 minutes early at all times. 
Yes, In my mind tardiness is a character flaw is a limitation, imperfection, problem, phobia, or deficiency present in a character who may be otherwise very functional.
Agreed. Tardiness will make even the most exceptional person in all other areas less than desirable. 
Tardiness is a legal reason for discharge in the work environment.  If only we could fine our friends!
I didn't know that. I do fine my friends in a way. I refuse to meet with them in the future.
Yes, me too!  That habit of being late is direspectful!
Incredibly disrespectful. If I can't cut them off I lie about the required arrival time.
