I have figured out a difference of working in small company v.s. big company. I was working in a small 25 person company before. Sometimes I came into the office and saw a pile of dirty dishes in the sink. I loaded all dishes in the the disk washer, added detergent, and then turned on the machine to clean them.
Now I am working in a big company. Today I came in and saw some toilet paper left in the sink. I said "gross, when will the janitor clean this up?"
