I see where there in you post where there maybe several solutions,,in more way than just a sprayer Myredracer. and yes your deductions are correct,,,and pretty perceptive,,,
"Walla is a word used by retarded Americans who don't know any foreign languages and barely know their own. The correct word they are looking for is "voila", which loosely translates as "here it is", "there you go", or similar meanings
You could not precieve the amount of back lash I have received in my lack of "barely knowing their own" language,,,much less than any other. I have been on the corrective end,now for several year back. Learned to take it all, as a given fact, and just grin, knowing it to be so. It is a fault, I will threw all of my years of this ribbing, agree with you, and you are not by any means, at this senior stage of my life, to be the first to point it out. Sorry if I have some how rubbed your fur the wrong way,,,accept my extended apology....John
