Customer returned back before closing times

Often I would pick up meals there and it seems like they doing customers a favour. On the door it is clearly advertised the trading hours. closing at 22H:00 during weekdays. But is not so, as per same ad. On the 25th. November I arrived at their doors at 21H:15, I was told the store is closed. i presumed it could be that there was no meals left or other reason am expecting to be communicated to. No! The shop is closed. People were standing outside, they came before me. I wonder if they arrived just before I did. Shocked and asked who the manager was? The security personnel informed me it is George on duty, with an attitude that may say \ what you gonna do? We still support KFC even after scandals. that shows continued loyalty and should be proud of customer retention for their service. please adhere to your trading hours! George ! It is disappointing to treat customers that way. At least you could have communicated the reason for ordering security to close so he can tell the customers. i wonder if you still got paid your salary this month?"
