Saw this sticker on an electrical box on my walk the other day. I do believe it is referring to internet signal strength but, it sort of sums up some days so very well.
Ha ha! I was delighted to tell AT&T goodbye when I got the fiber optic wifi with my local electric cooperative. It's much faster and much less expensive than AT&T, plus I get local folks who speak plain English without a thick accent when I call. =)
