Bad behavior

Today 2 Jan 2019 at 12:16pm at Epping branch when I got to the till after a long wait one of your staff ladies methaab comes to the cashier faieza and tells her to ring up her things before helping the client. The cashier faieza then go ahead and assist the staff member first without even asking if it's OK, neither apologized for allowing staff to jump the Q. This type of behavior is very bad for business. This complaint could have been avoided by simply asking the client if she could quickly ring up the staff's goods. Management please do not turn a blind eye and investigate this behavior
