Although it pains me to say it, I have been working in the retail industry for long enough now that I am no longer quite as incredulous at the level of contempt that the British public holds for sales assistants. There was a time, for instance, when the blatant discourtesy displayed by certain customers induced amazement as much as it did irritation - is she really discussing her private parts over the phone whilst handing me money for her daughter's birthday card? As time passed, this amazement gradually subsided and the irritation came to the fore - believe me, lady, I'd rather spend as little time taking your money from you as you'd like to take giving it to me, but I can only do so as fast as the cash register allows me to. Bitch. Nevertheless, as even more time passed, I found that I had become so accustomed to the occasional rude or disdainful customer that I could no longer even muster the energy to feel irritated by their behaviour. Meh. Now that I think about it, I suppose I had become institutionalised, for want of a better word. I had become the mindless automaton that those customers believed that I was all along. And yet today, in one fell swoop, one such customer changed everything.
