That is horrible that people can be so rude. By chance is it the lady who runs the front desk? (I know your vet)...Well, if it is I can promise that I can't stand her, LOL. I miss Judy the lady who used to work there but she retired/moved.
Thoughts and hugs to Gizmo today.
Oh, by the way...I left Ransom w/ his blanket also when he had a lengthy vet visit! It's just what Yorkie Mommies/Daddies do.
