Not meaning to attack you, Mio, and that does sound like an annoying incident on the bus, but your second comment made me want to chip in that I really don't like to hear the word 'fat' included in a description of someone's bad behaviour, or in a phrase that suggests that fatness implies ignorance or stupidity. Many fat people are extremely worried about their weight and struggle to lose it and become fitter, but have great difficulty doing this. Many are extremely well informed about the benefits of a healthy diet and exercise, as well, just not managing to put it into practice.

Not to say that this is, or isn't, the case for that particular bus driver, but I doubt if it would improve his mood to discover that he is known as 'the fat one' as opposed to 'the nice ones'!
