Merchandise or equipment damage due to rain will cost business to lose money as most of them depend on these materials to operate their daily business. Cost number three is the possible insurance coverage. Not only will business owners have to pay extra for the insurance, but waiting for an insurance claim to be settled on damaged merchandise and equipment could cause some business to close due to the inability to operate their daily business. This would be an additional cost for them to be at pride. So in the end I guess that it is indeed true what they say.
Nothing comes for free.
If anything just slap free on it. Then pass the buck off onto someone else.
