He goes to one house where the bin hasn't been left out, and in the spirit of kindness, and after having a quick look about for the bin, he gets out of his truck goes to the front door and knocks.
There's no answer.
Being a kindly and conscientious bloke, he knocks again - much harder.
Eventually a Japanese man comes to the door.
"Harro!" says the Japanese man.
"Hello, mate! Where's ya bin?" asks the collector.
"I bin on toiret," explains the Japanese bloke, a bit perplexed.
Realising the little foreign fellow had misunderstood him, the bin man smiles and tries again.
"No ! no ! mate, Where's your dust bin?"
"I dust been to toiret, I toll you!'' says the Japanese man, still perplexed.
"Listen," says the collector. "You're misunderstanding me. Where's your 'w h e e l i e' bin?'"
"OK, OK. " replies the Japanese man with a sheepish grin, and whispers in the collector's ear.
