「The hotel was very dirty - the table was full of dust when I first walked in and the rack where they put magazines is accumulated with dust.
There was hair stuck on the fridge door (on the part of the door where the label was peeled off).
There was a dirt stain on my pillow case.
I don't think housekeeping changed my bedsheets because I put one of the pillows in an awkward direction against the wall and it remained in that identical awkward position when I walked in to the room at night...
