if you take your clothes to a dry cleaner for example and they come back dirty, where you go to complain? youd take those clothes, shove em in their face, and say fix this.
Well if i was your dry cleaner and you did that to me... you would learn what my knuckles would do to a face.
You do know there is always a better way to do something that doesn't involve having the possibility of someone ripping into you or punching you in the skull?
You could say, "Sir/Ma'am, my clothing came out dirtier then when i left them with you, could you please do something about this, also i would like a refund since the job wasn't done to my desired standards. Thank you"
Jeeze guess no one taught you how to be civil did they?
