speaking of colored money, I remember the first time hubby and I went for a week in Canada..It seemed like we were always playing with monopoly money..reds, blues and the thing I noticed that differed from our money, is there was no attachment to it....our last day in Canada, the guy that waited on us in the restaurant got a huge tip/ all the canadian money we had in our pockets and my purse. Would never have given that kind of a tip in the states..
