Viewed from that perspective, I admit it may seem weird. I never thought I'd call Aswar "Curly" too.
I am simply deciphering the dive manager's logics and trying to demonstrate the absurdity I find in it :
Starting point : we will agree that Aswar gets the best tips because he's a nice divebuddy and as well as a skillful guide who's aware of the do and don'ts.
At the end of the day the dive manager looks into his crystal tipball trying to check who's done what.
If I apply the Dive manager's theorem,, we'll call Aswar "Curly" for the tips he collected, he will get reprimanded for cheating while he's only being so nice with his clients and found that rhinopias that wasn't seen for months because he knew from the cold temperature/the moon phase it would be around.
If I apply the reverse logics of the dive manager's theorem, Diveguide Moe (who's despised by all the rhinopias around for playing with his stick) didn't get any tip from Chilly because he was systematically poking the frogfish while trying to have it yawn, ...eventually he gets half of Aswar's tip from the manager's hand.
So in the end what I think is that tipping my guide is none of the manager's regard.
First off it's my money and I do what I want with it, i don't need to be patronized with shady tipping logics.(That also goes when I am advised giving a ridiculous 10% tip)
Secondly, I would rather advise the manager to do some management job (organizing work, motivating his team, training the newbies, listening to clients,...) instead of counting money which is either the accountant or the cashier's job. Who needs a operation manager that counts money? you don't manage the customer money in this position, you manage your team.
You know, I even think that this way of splitting tips equally is another mean for preventing explanations, in other words NOT managing the team.by explaining why Curly/Aswar had more tips than others.
