my office was exactly the same way. one woman was on CHIPS and claimed she ate no dairy but she apparently wasn't opposed to things that other people made with dairy in it! we had dozens of donuts, bagels, cakes all the time. i honestly never had a sweet tooth for cakes and pastries (pasta was my weakness, so if a pasta day ever arises that could be dangerous). they couldn't believe that someone didn't like to eat cakes & pastries! finally after seeing me not eat it for months they backed off and quit brining it around to my cubicle to offer it to me.
