Deep fryers. It isn’t the grease or all of that, i agree with Jeff it is the Air.
Nothing is more annoying.. That thick air produced by deep fryers or other grease equipment that your lung’s are just tired of having to work in that kind of environment.
When you arrive home to fresh air and anything you are trying to do that requires more then just sitting, your lungs will just say, ‘fuck you my work day is over’..

And i only on occasion help out, kudos to anyone working daily in that.
