Two friends, Mick and Dave, are having lunch over at Dave’s house when the conversation turns to postal delivery workers.
Dave, disgruntled about the subject, says “I order a lot of books to get delivered here daily, but I always get a slip saying that they missed me, even if I’m home to receive them. I’m getting sick of it.”
Mick, understanding his frustration, suggests “Maybe you should fight back, complain about it or something.”
Dave confidently replies “Don’t you worry about that. I’ve got it sorted today. I’ve put a sign on the front saying that I trade books for paint thinner.”
Mick confusedly asks “And how will that solve the problem?”
As though on cue, the doorbell rings and a man is heard calling out that he’s with the local postal delivery service, followed by some choice swearing.
Dave, nonplussed by the whole situation, wipes his mouth, stands up and says to Mick “Because I covered the front doorstep with super glue.”
