That complaining customer actually loves your business
there are those days when you go to your bank only to find it had closed 15 minutes ahead of time. On inquiring from the security guard why the bank is closed, he informs you that he was instructed to close earlier than usual without an explanation. You walk away bitterly; and with the bank closed you cannot access the suggestion box to voice your sentiments. So, the best you can do is only rant on social media
