It always bugged me that I couldn't edit typos in my title, mostly because I get really bothered at my own mistakes and if I can't fix it, I become obsessed!
The people not showing respect to the building would annoy me as well, though it might be less about the architecture itself for me. It's as much about the actual building as it is for the function of the building and those who work there. For example, even if I don't follow a religion or even have serious problems with some of the traditions, I should still behave well in a church or a mosque or a synagogue out of respect for the people who do believe and respect the function and the building.
