Chicken piece picked up from the floor and sold to clients

I am currently at hungry lion Alexandra Mall, and what I witnessed while waiting for my order was very dissapointing, unhygienic and disrespectful to the clients. A piece of chicken fell on the floor and the stuff that is working in the kitchen picked it up and returned it to the tray that had chicken to be sold to clients, and rhe worste thing is that when the kitchen stuff realised that I saw what they did, they did not even bother to remove the chicken piece from the tray. Zero respect for their clients.
