Tom & Mike,
Where do foursomes of golfers, no matter how diverse their games, congregate 36 times in a round ?
The tees and the greens.
That's where the golfers congregate or become concentrated during their round.
They can be all over the body of the hole, but they tee off together and come back together to putt on every hole on the tees and greens.
As such, while waiting their turn to play, they have ample time to obverse everything in close proximity.
Ergo tees and greens are the most visible features to the golfer.
So, if your tees aren't in good shape, that poor shape will be observed and impact the golfer's impression of the golf course. Repeated 18 times, that impression become indelible.
Ask yourself.
When you go into a restaurant, a restaurant with good food and good service, how often would you go back there if you walked into the kitchen and found it to be in poor or very poor shape ?
Even if the kitchen was in good shape, how often would you return if the rest rooms were horrific ?
So visual presentation is a critical factor in terms of appealing to the golfer.
Neglect the tees and the visual impression will come back to haunt you.
