Just imagine someone taking out a cup of sand they safekept from your store. They wanted it delivered to their house which is 20 miles away. Obviously, the gas prices aren't cheap, so are you going to do this service for them anyway? There are operating costs to every service, and if you think 50 cents is much more valuable to get compared to the fee that you are about to incur, then you may have a few screws loose in your head.
