Bad service

Went to go buy a few drinks today, went into the store at 14:55, while I was busy inside I was advised you vacate the store since they close at 15:00. There's a Gentleman that came after Me but was allowed to make a payment.The Cashier shouted at the security guard for allowing People to walk into the store.We are being treated as if we are not paying.
