in England a 'friendly' means a game that isn't part of a competition (a league or cup). A friendly is a fixture arranged between the two clubs (or schools) and played just for it's own sake.
friendlies are generally slightly more relaxed - but not necessarily - they can really vary.
At one extreme is a pre-season training game, which might be very ad hod - 4 x 20 minute sessions, squads of 25-30 players, rolling subs, coaches trying different combinations.
At the other extreme is the annual derby game that you might traditionaly play with your biggest rival , which is as serious or competitive as any league game.
Ok - I knew what a friendly game was, just wasn't sure what you meant exactly when you used it in reference to the club game. Thank-you for the explanation though - tells me something about the game being slightly differently run in different places
Essentially for us in Sydney all junior club games and most of the senior rugby is part of competition of some kind (or at least all the rugby I've ever been exposed to here is!) and most schoolboy games aren't necessarily part of a competition but are still played quite seriously as if they were any other competition match (or at least IMO would be considered a friendly - having played them before).
Marauder - I'm with Crossref - it is our job to apply the laws (of course it is also our job to interpret the laws - with guidance from the various referee associations, the IRB etc.).
Just my opinion to the ideas you put in - if a player picked up the ball and just ran with it (I'm assuming this is a player who, by his actions, has obviously heard and noticed the referee blowing his whistle) there could also now be at least one additional sanction that I can think of off the top of my head - FK for time wasting in addition to not taking the tap correctly.
Regarding mark of the tap - there is no sanction listed in 21.2 for the team failing to take the penalty at the correct mark and therefore I would understand there can be no sanction for it except being made to take it again at the mark unless we want to make some new sanction exist. For a kick into touch, as long as it's within a half metre or so of the line of the mark, I'll be happy and the same applies for a tap - as long as it's behind the mark. To the part about taking the tap before a mark is given - The players must wait for a mark to be given to take the tap - unless I had stated otherwise in the PMB (e.g. take at last feet of scrum when scrum penalty if you want to take quickly)
EDIT: This has moved a bit
