what's the meaning of self-conscious in this sentence ?
A pretty waitress, self-conscious in a mobcap, arrived to top up their glasses.
Is that a waitress wearing a mabcap, and went to her guests, and poured their glasses with drink?
But what's the intention to use "self-conscious" ? Is there any possibility for her not to be self-consciious to know she should top up her guests' glasses ?
