Ummm, it's not "E voila!"
It's "Et voila". I can understand (maybe) not having the proper letter "a" (even though it's in the Character Map program). Heck, this ridiculous BB Code won't let me use the proper a with the grave accent. But to leave out the "t"? Surely you must have Google available in your office to check spelling of foreign phrases, no? I mean, why use an unnecessary phrase without being absolutely sure that you've gotten it right? It already seems pretentious to use "et voila"... and to get it wrong just makes it seem that much worse.
