This old bloke is on his first day as a postie. He’s never managed to keep a job more than one day because he’s abrasive and rude. It’s immediately obvious why he’s constantly getting the boot just by chatting to him. It’s somewhat comedic, though he can be a bit startling. Currently, he’s working at the post office and sneaking a look at people’s mail before handing it over.
