Don't care attitude

Went to purchase cigarettes from the kiosk and pay for a few other items at the same till only to be told that the till is locked and that the manager has the key. I waited for 15mins and was then informed that the manager was in the toilet. I got upset and left everything behind and informed the indian guy at the till that im going to be reporting this to which he rep**** \do what you want to do"he had a stinking attitude. Why was the till locked at 18:25 when the store closes at 20:00? I sent an email to pick n pay customer service"
