Remember, it's for our safety
Don't get why they wouldn't want to change gloves. I keep hearing annoucements at ORD about washing your hands when you sneeze or touch certain things. For all they know, somebody could be wearing very dirty clothing, infested with some sort of bugs. Great, looks like they've just spread it to 50 pax...
Ron, SATTSO, Bueller? Care to chime in?
