I'm from a small town too, but when I had fish shipped in when I lived in the smaller town, even though everyone knew my name, my cell phone number and my home number, they still would not open the box to make sure my fish were alive, even though I always made sure to open it there to show off the newest fish.
As for being rude, eh, it was probably more tactless than rude, I doubt she really meant to be rude.
Either way, it's done and over with, the chickies are home, and oh my god are there a lot of them! They're safe and sound and probably loud as all get-out!
