Sorry dude, it's the reality of hotel living and they need to consider things like this. Details matter.

Explain why they button up the back pockets of the pants?

You don't need to unbutton a collar to wash them. How many people unbutton collars at home? Betting 99.9% do not. Your skin doesn't even touch it...

And I see you added the unecessary comment about the mosquito. In fact, I am PAYING Marriott for laundry service and not getting what I want. I also believe most men would prefer not to have to keep buttoning collars and cuffs each day.

This is the service industry. It's the small details that make a difference.
