Free Lunch

I was always had the opinion that there is no such thing as a "free lunch".....and thats what they teach in corporate management training sessions. But I guess I would have to change my opinion especially after I came to USA and joined Drexel University...I have been having a free lunch every alternate day......either a pizza or a pretzel, sometimes cakes, sometimes cookies but there has been a free luch atleast twice a week since college started....and I believe there will be many more free lunches like the one i had yesterday...it was a party for all the TA's of the Physics Department.....so if u r a student and u r in Drexel University then u can expect "free lunches" at the start of the Fall term.....but now I am off for a "paid lunch"...
