I have some office feeders who routinely bring donuts or the like. "Did you get a donut? " "Thanks, but I don't want one." It's not that fucking hard. People act like it's hard to say no. I don't know why some people bring food to work. I assume to get people to like them. I've never had anyone give me more pushback to a "no thanks" than a, "oh try one," that ends quickly with a polite but firm, "No thanks." The idea of endless hounding is total fat fantasy. In the real world everyone knows that pushing beyond a no of an unsolicited offering makes the pusher the total creeper. It's not that fucking hard.
