I've seen this at various hotels and resorts in the past. I ALWAYS make them take it off... especially if they don't ask first and just "presume" I want to participate. I know $1 isn't much (one time at a resort it was $5) but I don't want to donate to a cause I am not familar with, haven't researched or might not want to support. I REALLY find it disagreeable when I read later in the press or on a webiste how much thsy have donated to charity.....they didn't donate it, thier customers did!
