You own a queue and regardless of where it is, there is a certain etiquette and responsibility that comes with being able to form a respectable looking queue. Some of your pet peeves consist of people who push in (get to the back before the rest of us tut loudly and make you feel ashamed) and people who just don't understand the queuing system. Make a straight line, don't stand too close to the person in front of you and always let the elderly on the bus before you, but not if they expect to get on the bus before you - they have to wait for you to offer. Rules.
