What's up with people who park their bikes on bike racks parallel to the bike rack instead of at a 90-degree angle (ie perpendicular) like you're supposed to? Their selfishness/stupidity hogs up the entire bike rack if it's only built to park 6 bikes or less. Are these people congenital assholes, mentally defective or are they just suffering from the old "dog in the manger" complex? Inquiring minds want to know, not that the answer is likely to be of much use to me or anyone else...
