So, rather than keeping to the right/left so that people can freely walk past you, you decided to take up more room to prevent people from overtaking you? I don't understand people who do that. It is one thing when people are trying to shove their way past you in a queue but it is unacceptable when people take up all the space when walking expecting other people to keep their pace rather than maintain their own. Some people like to walk fast you know...
