So what do you do with the spoils once you're finished spooning or forking your rectum? Deposit it in the toilet? Put the cutlery in the dishwasher?
The cutlery is for eating as opposed to using "the right hand" as Iggy suggested.
We wash our arses with soap and water using the left hand after taking a crap, likewise our genitals after urinating.
The smell on public transport from the unwashed sh1t smeared arses and p1ss stained underwear is awful, especially during the summer months.
I don't think the smell is noticed by those dirty unwashed people though.
