Pathetic experience

I walked into Pick n Pay with a sealed mr price parcel i just collected. Did some grocery shopping when i realized i need to go to the ATM to get money that was ewalleted to me. I parked my shopping cart at the back so that my cart doesn't get taken away because i was coming back, as i walked out to go to the ATM. I get stopped and get accused of *****ing and my bag needs to be checked WHICH WAS COMPLETELY SEALED. Maybe train your staff to stop accusing people of *****ing and provide better customer service and looking like they hate their job.
