Obviously she was too busy to notice. Anything. In some shops the staff get so engrossed in their own conversations that you might as well leave...
The local post office has a charming lady working there, and whenever I pop in to collect the mail from my box she chats away on personal topics regardless of queue build-up. I get embarrassed to make them all wait, but she's as happy as you can imagine and laughs all the way. It's like that here, and if in a hurry drives you insane but otherwise, it's enjoyable, especially if you can make out what they are all going on about.
