Cosmopolitan of Las Vegas

I don’t know if this is standard practice with housekeeping but I was not pleased at all. I was in the room when they tidied up our room because I just wanted new towels and trash emptied. They did have gloves on. They did tidy up our bathroom, took the trash and towels, then proceeded to make one of the beds with the same dirty gloves! Smoothed out the sheets and pillows etc. Do they change gloves before each room or transfer dirty gloves from room to room? Lesson learned, no more housekeeping, I will just ask for fresh towels from now on!
