I was in Rome at an SPG property and they did this very same thing except it was to Unicef and in Euro's but it did Pi$$ me off enough to tell them to take it off and I told them why which was I don't like the idea of them just putting it on the bill and leaving it up to me to remove it. Had they asked at check in if they could put it on or just 1 euro or something, fine, but to do it this way, no way.. I will not do it and it leaves a sour taste in my mouth.
