And sometimes the process gets too irksome. If you have to reach for and unlock three different doors just to get in and out of a place you frequently come and go every day, you'd start to consider that excessive, wouldn't you? Especially when you frequently do so with your hands full (where in the job description did it require such people to be jugglers). Security may be a process, but it has to compete with ease of use. Make things too difficult and people are going to go, "Screw this! My livelihood ain't worth this much hoop-jumping!"
