Disgusting service

Went to pep home on the 15/14 July after 17:00, there was a young lady Zonke mopping the floor which had no trip/wet signage. While I was on the line to be served I heard the young lady Zonke (works at pep home protea gardens) say to a customer some customers are disabled, can't they see that the floor is wet, I then responded to her politely where is the signage to show floor is wet and why would you call your customers disabled. Zonke then rep**** very rudely that there is no signage and can't you guys see that it's wet on the floor. I then explained to her the seriousness of not having signage but she was too rude to even hear as she kept on saying it's not her problem and if I want to report her then I can go ahead her name is Zonke. I would like for Pep to visit recruitment process and invest in training of customer service to their employees as they lack that
