I'm going to recommend a new employee iron her clothes
Why would you tell her to iron her clothes?
I didn't let her reschedule her interview, but she's showing me her trousers with a big coffee stain...
She may not know the stain is there, so it's helpful to point that out. It's best to do it in a polite manner so as not to hurt her feelings.
It's a joke, a social experiment! I'm sure she'll laugh when she know..
I'm not so sure that she will laugh. I think you should just tell her about it in private to avoid her getting embarrassed.
