I think it's okay. :) It doesn't sound to me like they were bothered by the bread. If someone really, really didn't want you bringing in food, they'd tell you. I've never been in a working environment where food was not welcome, and if someone didn't like what was brought in, or for some reason their diet wouldn't allow them to eat that kind of food, then they simply abstained. Not your fault people don't have willpower! :p
