Every Time I visit Subway or any other sandwich shop..Why is there always somebody in line CONSTANTLY texting?....And they aren't taking the order...They order ONE SANDWICH and eat it there...

I swear there were two young women in front of me and they were doing SO MUCH TEXTING..The lady behind the counter had to ask them twice..WHAT DO YOU WANT ON THIS SANDWICH?...Don't they realize some people only have a CERTAIN AMOUNT of time for lunch and they are up there texting away....One of these days...
