Unannounced and expect to be shown round?
Friend in question is looking at a private school for her DC in a couple of years' time. She was in the area and dropped in on a school she'd had her eye on for a while (complete with buggy) 
When she was telling me about this yesterday, she said the staff seemed quite hassled and there wasn't anyone available to show her around. She waited for a while and did eventually get shown around (by the receptionist) but she just felt like she couldn't ask all the questions she wanted to.
I said (nicely) she should have made an appointment so that the school was ready for her! I likened it to dropping in at the GP and hoping to be seen there and then. She's now taken the huff with me.
AIBU?
