Would you allow these to be used on you?

So I had an appointment today to get a couple fillings filled. The assistant came and got me and brought me to the room. They had a sterile pack on the tray that they opened immediately without washing their hands or putting on gloves and just threw them on the tray and left. I felt uneasy with how they handled the tray/instruments and looked and they had rust on the forcep and cement (not sure if that’s what it is). And residue left on the drill. I didn’t stay of course and will bet treatment elsewhere.

Is this normal for dental offices? I work in a hospital setting so im not sure if they do things differently. I know the tray would have been rejected if it had all that rust on their instruments up in the OR.
