Soo I work ~8 hrs/day at a coffee place so I'm always running around and I was wondering if anyone knows how much that would affect a daily calorie burn compared to the less active days I will have when I move back to school in the fall.
Background : I'm a 19 yr old female, 5'4" 145 lbs.

Thankss

According to Fitday, at your age, height and weight:
Strenuous work or highly active: 2,695
Standing work: 2367 cals
Seated with some movement: 2148 cals
Seated all day: 1874 cals

I think the calories we burn outside of formal exercise make a huge difference. I have an 18-month-old son -- a trainer at my gym asked me today, "How many times do you lift him each day?" Oh, about a thousand! It adds up...

Edited: Ooops -- sorry, those numbers had my weight plugged in, so all the figures would be just a touch higher, but you get the idea of the difference...
