It will depend on the type of business.The opening of the doors of the business has been debate for long time as to who is responsible for the opening of the doors of a business one school of thought says its the responsibility of the a junior staff (the gate man or security) others say its the owner of the business but as for me it depends on the type of business is it a sole trader or a partnerships type and also it depends on the structure of the business so the two I mentioned above can open the doors
As a sole proprietor, I am expected to be the one who open the doors to my business everyday.
But when it comes to an organisation, a security man or gate keeper is hired to do the opening and closing of doors.
