Never unless it's an absolute emergency. Luckily my shifts usually are short, but it's tough when they're not too. I don't even like ****ting in the morning before work, because I don't like feeling rushed when pooping. I'm so anal (no pun intended) about pooping, that I even have a mental list of acceptable places to **** around campus. I know which floors of which bathrooms are basically deserted, and go there.
Love pooping at work. Toilets there are nice and big. Much better than my apartment where there's this tiny ass toilet that I can barely fit my junk in when I sit down.
About twice a week. Is there any particular reason you made this a public poll, OP? Also three times a day? The ****? Do you live at work, or do you not have a toilet at home?
For 6 months I have been pooping in my coworkers coffee. I climbed up on top of his executive chair on to the desk, grab the horn of his taxidermy cow, other hand onto the american flag and voila! He post here, mainly in the d&d section.
