@Hooroo yeah Sergio is pushing it...
Oh for sure, plenty are gimmees all day every day, but guess it depends how well you know the person and if there is the unspoken acceptance of it as well..but in big tournies peoples are often tougher on them and require verbal acknowledgement...oh, and matches with your mates with beer on the line, cnuts can putt them all day long!
I played in a quadrangler tournament one time, and was 1 guy from Auckland we played, he didnt give a single putt all weekend, even those sitting on the lip, but everyone knew he was like that so putted everything out.
