A little bit unfair, I think. When it comes to wanting their pound of flesh, Shylock has nothing in comparison with call centres. I worked in one (and to be honest I quite liked the routine, till they decided that it was cheaper to give my job to someone in India). However, when you work from 3pm till 11 pm, as I did, and the last bus goes at 11.05pm, then every second counts. If you miss the last bus home the taxi fare comes out of your pocket, not the company's. At the time the taxi fare was equivalent to two hours' wages.
