i own a small business that i run almost by myself, but i wont make excuses for the owner, it does suck to drive there and have him closed but i don't think putting a sign on the door would of helped, because you still would have driven all that way. plus even if he posted online, you might not have checked anyway. but you sure have the right to be upset, and i would be too, but hopefully you give the owner a chance to make it up to you, because to error is human, but to forgive is divine
