Germany's Marcel Siem provided a perfect example of his attention to detail in his final practice round ahead of The Open Championship at Royal Lytham.
On reaching the 18th green the 32 year old chose to practise rebounding chip shots from close up against the clubhouse wall back onto the green.
In his preparation for the eventuality of overshooting with his approach to the last even just a few feet Siem also noticed that the ball reacted differently depending on which part of the 112 year old clubhouse he was hitting against.
"When I was a kid, 15 or 16 years old, we did that in the Lytham Trophy and it is definitely a possibility the flag will be back right," he said.
"The shortest possible shot to up and down it [is against the wall] so I wanted to get a little bit of a feel of how to do it.
"The bricks are a little different - the middle ones are softer but the ones on the right are very firm so you have to hit it a softer and it comes back easy."
Golfers are well-versed in playing every type of shot and Siem is more than comfortable attempting something more out of the ordinary.
"I grew up like that, I was always trying stuff," he added.
"My parents ran golf restaurants so my kindergarten was the golf club.
"I was doing way more stuff than that (rebounding balls off walls).
"I was hitting it against a buggy and bouncing it back and a bit of golf billiards on the course, hitting it against other stuff.
"It is still a game so you have to enjoy it a little bit."
Siem's victory at the Alstom Open de France two weeks ago secured only his second appearance at The Open Championship, his first coming two years ago at St Andrews, involved some last-minute arrangements.
"It got a bit expensive sorting out a house as we were a bit late but I've got my mum and dad and coach with me in," said the German of his accommodation expense - although that was more than offset by the €525,000 he won in France.
"My mum is cooking for me and it's a long time since she was cooking for me every day."
That victory at Le Golf National also played a key role in Siem's mindset.
"Two years ago (at The Open) I was a bit nervous, thinking: `Do I belong here'," he said.
"But this morning I said: `I do belong here because I won a tournament and got the spot in a proper way`. That is the difference I think."
