Am I out of line here or should dealer have been pulled?

[Zybomb]

AC Casino not an underground room or I wouldn't be posting this....

4 Way raised pot

Flop comes all diamonds and its checked around

Turn is a black king

River is a diamond

Checked around and a guy shows a pair of kings, no one else does anything for a second although no one mucks either

The dealer then actually says out loud: "Does anyone have a diamond?"

No one even flinches or acts like anything wrong just happened except me and im like ?!?! uhh "What are u doing?"

I told her to call the floor...they come and after hearing what happens say to her "you really shouldn't do that" and then leave

Is this fair, or am I out of line thinking she should have been pulled from the shift?
