She probably just sees a lot of people wanting to volunteer and gets tired of hearing everyone's stories and why they want to volunteer, etc. I get really sick and tired af hearing about people's pets when I'm at work.

Unless it directly pertains to the question they're asking me, I don't want to hear a bunch of stories about customers' pets! After awhile most of them start to sound the same, and I just get frustrated. When this happens I do my best to hurry and finishe with them so I can move onto the next person.

I don't think the woman was being stupid, I think she had to deal with idiots who didn't care enough about animals all day every day, and was tired of hearing the same thing over and over. I think she probably is less than happy with her job (as anyone would be with any job from time to time).
