From urine in the whiskey bottles to dirty bedsheets and what not to do with the ice bucket, hotel employees have revealed all the dirty secrets of their establishment in a discussion on the net. Here we share few of them.

Use a towel or sheet on the chairs or sofa. A lot of people sit on them naked. It''s nasty but there is often a brown streak on the chair. (Thinkstock)

Mattresses will be stained, with a lot of stuff. There''s no way a new mattress could be bought every time someone bleeds on it. (Thinkstock)

Check the seals on the things in the minibar. You never know what you get..maybe a bottle of urine instead of, a bottle of whiskey. (Thinkstock)

The glasses/mugs are usually just rinsed in hot water in your bathroom sink. So next time you need a glass, just ask for it. (Thinkstock)

If you book a jacuzzi, be warned, the jet system of the hotel is often completely clogged up with really nasty gunk. (Thinkstock)

People think a doorman is just a doorman. But actually they provide services of a bellman and valet at a resort. Can give you tampons, valet parking, shuttle rides, reservations, dry cleaning, and even an upgrade to a better room., if you just 'ASK HIM'. (Thinkstock)

Do not use the ice bucket without a liner. It may have been used as a puke receptacle. (Thinkstock)
