No, I'm not someone who asks the "guy" handing out weights how much I need. I know exactly how much weight I need. Nor am I a "tourist diver" or someone who skimps on tipping people. It NEVER crossed my mind to tip the guys that fill the tanks. Until your post (which I found rather rude), I had never heard of that before. Furthermore, I have never stayed at any of the "dive resorts", so my interaction with the people that work there is very limited.
If the post was found to be rude,sorry about that, for I usually am not rude,being the very empathic person I am...But, I find it EXTREMELY rude of people to not leave a gratuity for the staff who help them to have an enjoyable stay at their location.
Also at your experience level of something like 100 dives I think you really should consider yourself a tourist diver.You do not work there or are not an instructor leading a group completing any training.
