This is a very nice idea. We can ask some stores to do such kind of charity instead of donating cash. They can give store discounts to people who deliver transporting food. Money motivates people. They will do it.
This is a nice idea. This will surely ensure lower food wastage. I have tried this before and following are the few challenges I faced. 1. The quantity of wasted food varies day-to-day. The time between when we know that there is less food to when the homeless people arrive for their meal is very less. We, sometimes, had to prepare some extra food by ourselves to make sure no one goes hungry. 2. I also learnt that giving out free food is not a sustainable solution. It does not empower the community. People get into the habit of free food and they feel entitled. That is when we really started charging for food. Very low price. Almost 10% of what the restaurant would charge. But people were not ready to pay because they wanted free food. Then we asked them to help out in distribution and cooking and gleaning. But they did not want to do that too.
Thank you. And you are right. We will have to find a way to implement this without causing discomfort to the customer. We may use a part of the restaurant only. Or we will float this experiment for only a stipulated amount of time. It is about creating a movement. If ice-bucket challenge can be a sensation, this can easily be one. :)
