I hear this often,” yeah I saw the sign, but it doesn’t pertain to me”. Says who? You are not exempt. The signs pertain to everybody equally in every building, every street, everywhere. Businesses have signs for a reason and they also have rules, the rules can change often. It’s really not that hard to be respectful in a place of establishment, if you cannot read ask somebody what the sign says. I wonder every day if you can’t read signs, how the hell did you get here.
