I ask you!

What is up with the random apostrophes? I mean, really. I know this is a small pet peeve of mine, but seeing random apostrophes drives me mad. They are added to show possession, therefore, operator's does not need an apostrophe unless there is an operator possessing something (e.g. the operator's phone, NOT the dog's are running around). Don't <----another example to show a combined word do + not. This is my English lesson/rant of the day.
