I'm at the office today and was heading to the toilet when I noticed a young delivery guy waiting outside a locked door carrying a large pile of boxes. So I headed over with my door fob and swiped to let him in, holding open the door so he could go through. He didn't even say thank you or acknowledge me, just hummed a tune as he went in. That's so fucking rude, manners cost nothing.
Just needed to get that off my chest. Grrr.
