AIBU to think that the staff who answer the phones at the school office (secondary) could be a little more gracious and not sound, every time, as if they are doing me a favour. Conversations go a bit like this:
them: "blah blah school"
me: "hello, this is Mrs blah, please may I speak to ....., I am returning her call"
them: "she might be teaching"
me: "well she might not be so would you mind trying"
them: "there's no answer - you can try again later"
me: "I am returning her call, please give her a message and ask her to call me back"
No please, no thank you, no hello, no appreciation that they are there to provide a service and to represent the school's image. And this is a school that prides itself on the good manners and excellent behaviour of its pupils.
