He completes 3 more holes then realises he now has 15 clubs (actually started with 14).
Greg, immediately (and correctly) takes his 7-iron out of play, then continues with his round.
Greg is disqualified.     [REF: 4S1534]

Playing stroke, Jill's ball has come to rest on the fringe of the putting green.
Without reason, Jill lifts her ball without marking it first, cleans it then substitutes a different ball and places that on the spot of her original ball.
Realising her error, Jill marks/lifts the substituted ball and replaces it with the original ball then plays that to the putting green (removing the marker first).
Jill gets just 1 penalty stroke.     [REF: 4S1518]

Liz is playing stroke and carrying her own bag (good healthy stuff).
Whist playing a hole, Liz stands her bag near her ball.
Whilst working out how to play her next stroke, a gust of wind blows the towel that Liz has placed on top of her clubs on to her ball (at rest in the general area) causing it to move.
Liz gets a 1-stroke penalty, and her ball is replaced.     [REF: 4S1446]
