Calorie counting, MFP users!

I've been calorie counting for a while using My Fitness Pal.

I recently got a super part time job as a waitress in a retirement home. I work for 3 hours at a time serving seniors their dinner and desert.
It's a restaurant type setting and I'm walking the entire time.

But I'm wondering if I can count those 3 hours of walking as 150 minutes (2.5 hours) of walking leisurely pace?

I work as a CNA mon-fri 7-3:15 and I don't count that because its my actual job. lol

I work at dunkin donuts, and for an 8 hour shift I usually put I'm 3.5-4 hours of cleaning (light /moderate)

I just up my "daily lifestyle" to moderately active which ups my caloric count.
