I hate these.
One went up in the windows of a cafe that just opened in my 'hood a month or so ago. I don't think they have posted their hours of operation yet -- they just have this.
Fuck you, cafe in the 'hood. I don't have the phone or the app that handles this jibberish. So you don't have my business.
I also saw one of these beasts on the door of a medical van today. Graphically, I think it's comparable to a cigarette burn in the middle of a crisp, white shirt. It looks like an accident. Or like the residue that remains on a product after the sales sticker has been pulled off.
And how does this work with a growing number of States banning the use of cell phones while driving? I guess this medical van in the lane next to me is only seeking the business of pedestrians with fancier phones and apps than I currently possess, too, yes?
