I was on the bus earlier today, en route to what turned out to be a lovely lunch with my family, when I noticed a new sign above the exit door. It encouraged passengers to shout thanks to the driver in whatever way they liked as they left the bus. The examples the sign gave included “Thanks driver.” “Cheers.” or “Ta.” I have, of course, noticed my fellow Londoners shouting similar things as they get off busses – it’s sort of the local custom, usually in their thick London accents – yet I hadn’t seen anything overtly encouraging it. It made me wonder whether I should start doing so too, but how? It was then that I had one of my amusing ideas: Perhaps I should start shouting the Klingon word “Qa’pla!” at the driver as I get off busses. “Qa’pla” technically means “Success!” but it can be used as a way to thank someone. The bus drivers won’t know that of course, but, then again, most of the time they won’t understand what I’m saying anyway. That, then, is what I plan to do from now on. After all, what’s wrong with introducing a bit more Klingon into your daily life?
