Nan's funny note

Marlene from Glasgow decided to quit her cleaning job and in her letter informing her boss at her cleaning job Mr MacGillivray she vented her frustration towards him, and wished him luck finding ''some other mug to clean the place'', according to The Daily Mirror newspaper.

Marlene wrote: ''The joab's c*** and I'm leaving. I'll no be back after June 30. Canny wait.

''Good luck getting some other mug to clean the place. Cheerio.(sic)''

Marlene's granddaughter Kaitlyn McGrory shared a picture on Twitter of the message, and her honest grandparent was dubbed a ''legend'' by social media users who retweeted the post.
