Grumpy old ladies

I've met some of them mostly during weekends. They love to have plain hamburgers with tea as high tea. They only convey their messages once. Unfriendly stare and pursed lips are most likely if the word 'pardon' is heard. There are exceptions of course, just that I've lost my patience and the ability to keep the corners of my mouth curve upward today. Sigh, I feel like I'm one of them today.
