It is sort of like when you take your new car back to the dealer to point something out and they reply, "oh they all do that." Somehow they think that is going to make you feel better. I call it the "misery loves company principle." If you aren't the only one going through it, somehow that lessens the pain and you feel better. You still have the vibration or in your case have unwanted vents but it gets a lot of people out the door or off the phone. I wouldn't wait until they are gone before lighting that candle. Put their feet in it if you have to.
