Saviour the Sirloin Burger

I drove by that the other day. I noticed it about 3/4 to 1/2 a block away and wondered if they did that on purpose, as if the sirloin burger was a saviour, or perhaps they were trying to be ironic. Or, lastly, did they just not know how to spell?

I drove by later in the day and it was changed, so I guess it was just poor spelling or a poorly received attempt to be ironic.
