And hopefully one which isn't too Ni-focused like my previous ones.
A woman is alone in a pub (or bar) that is rather busy on a Friday night. She has to wait for quite some time, standing, among other people waiting to be served, until the bartender rather hurriedly (but still very politely) asks her for her order. She asks for a pint of a particular brand of beer. A couple of minutes later the bartender takes her money, gives her the change, and hands her her beer, all very quickly. He then turns his attention to one of the many customers standing around her, waiting to be served. Only then she realizes that the beer she got was not quite what she had ordered, and that, being 20 pence more expensive than her original order, her change was accordingly smaller. She ended up paying slightly more for a beer she didn't order. Yet she decides to say nothing and walk away with that beer.
- what thought first comes to your minds as to the woman's motivations? Why didn't she complain to the bartender to get what she had actually ordered - in terms of both brand and price?
