why do hotels never wash there blankets

[Chris2597]

I always turn the bedspread and blankets down before even sitting on the bed in a hotel.....I also take my own pillow from home or on occasion use a fresh bath towel on top of the pillow....I have also been cold in a hotel room because I wont use the blanket....I am going to start packing a blanket.....I am glad to read that I am not the only one that feels this way. My family thinks I am over the top about this one.
