Thanks everyone!!
We appreciate all of your input and help!
We will take each reply and suggestion and figure out what we should do, moving forward. We kinda feel bad for our guests, as everyone makes mistakes, but the packaging, travel to the UPS store (the post office lines are around the corner in Chicago sometimes, so there's no way we can do that without pulling out all our hair!) the cost for shipping, the time involved for all this before our workday starts, seems too much sometimes.
But, we don't want the possible lesser review, so we almost feel trapped into doing all this so much, so far. Hopefully our future guests will pay more attention to their stuff.
thanks again everyone!!
