Speak up if you feel someone is taking you for granted today, let them know you wont put up with it.
If you feel like someone is taking you for granted today, do not just put up with it, speak up and say how this feels. Part of the problem could be in that you too often do not speak up and push back against this behaviour and if you act like a doormat people will treat you like one. Show others that you wont be used in this way and you will be treated better.
