Given the context of his "requests", I must say I find it a little hard to believe. I mean, when you're in a restaurant it makes sense that someone, even if they have a super-thick accent, may ask for a "fork" instead of a "fuck", right? Waitress must think really highly of herself to think the guy wants to fuck her instead of eat his meal that SHE JUST BROUGHT TO HIM!
Then again, these people could just be the Maltese versions of the "dumb blonde".
