Really? For more context here is the entire paragraph:
"Barnaby chose my company's ATM arbitrarily, it was just the most conveniently available to purchase on the web and be delivered to his home. Note to our salespeople: for security purposes, please make it more difficult to purchase our product."
The whole article is thick with sarcasm? The only other bit of sarcasm/joke in the last nine paragraphs is that the author booed/jeered barnaby when he came to the stage. If "the whole article is thick" with sarcasm why is the last 37% so straight forward and not funny?
It comes directly after the line 'Barnaby is from New Zealand and I'm from Australia, and trans-Tasman friendships are regarded as treasonous', which FYI is also a joke.
