Americans are paranoid when it comes to lavatorial hygiene. Nearly every khazi has a dispenser for toilet seat tissue covers and there are even a few I've seen in New York with automated plastic toilet seat covers. Go figure.
Company offices in the US usually have a waste bin by the door, so you can take a paper towel to hold whilst you open the door handle and then lob it in the bin. Our UK office doesn't, so instead by mid-morning there is a pile of screwed up paper towels on the floor by the door.......
