I'm not sure about how this sounds in the English language, but if I read this in German language (my native language) it sounds bad.

German people don't like to discuss the death. I guess these advertiser are not Germans...

I just took German in school for a few years and even I can tell how bad this is. "wirts"? Is that even a word? And that does sound a bit straightforward. I can't think that would sound any better in English. Wouldn't a PR department probably want their ads to make sense? I could understand it if they used Google Translate and used the formal tense, but this is kind of strange.

Well spotted Philipp! Could this be the beginning of German lolspeak? Deutschlolsprache

There are loads of bad (funny) machien translation examples. My blog has a few.

Email spammers are even using this to seell to new markets.
