Online Food Apps offering free food on late delivery

In modern day world we people being little lazy or rather than saying lazy we can say busy have made online food delivery a trend. In order to avoid making food or washing dishes we just open our cell phones and choose our favourite restaurants and simply order the food. And obviously we are aware about the free food policy of some of these applications i.e. if the food is not delivered in 30 minutes then we will be offered free food. But this really happens? In my opinion and also experience such policy is offered in rare cases, this happened with me too I ordered pizza and was eagerly waiting for it then as per their policy they were to give me free food on delivery after 30 minutes, when delivery boy arrived after 45 minutes i cross questioned him to get FREE FOOD but he gave me reason that he will be charged for late delivery then i for the sake of humanity gave the money thinking that he is working hard for earnings.                 ...
