Regulars saying "I know you're off but...." and then asking to see you, if you can squeeze them in on one of the days off etc. Made even worse with the one who said it to me recently as he knows I am off because it's school holidays and I'm a mother, so will be well aware I will be spending the time with my son. If I work then I'm not off am I? And like hell I would palm off my son for a few hours in order to see a client!!
