So much needless snarkiness and rancor about tanks. If you have an antique, don't expect your local LDS to fully understand it. Many of these employees are younger than the gear you want them to service or fill. I was in automotive from 1969 to 1999. I saw a lot of changes over those years and it amazes me how little a modern technician understands about the old days. Asking a mechanic to install a set of points and condenser with a setting of 32
o dwell will elicit any number of responses today... and mostly a puzzled "what-the-hail-you-talkin'-'bout-Willis?" look. They don't get it, because they didn't live it. Consequently, I have a bold 2250 in sharpie written on my 72s because I don't want them to overfill them by mistake. Heck, when I had surgery on my right ankle, I had the kids write "NO! NOT THIS ONE!" on the good ankle. Why? Because I am my own best advocate. I know what I want and I gently communicate what I want with all candor and good humor. When I get something different than what I expected, I don't merely assume that the other guy is incompetent. My first thoughts are always about how I might have failed at communicating my needs and desires and rather than point fingers, scream or cry foul, I try to discern how I could have communicated better so I can get what I need/want.
We live in an ever changing world with very conflicting messages being sent to our dive shops. Do it fast. Don't do it fast. Give me a really "good" fill. Don't overfill. Do you really expect the LDS employee to remember your preferences? You should be your own best advocate and realize communication is a two way street. Tell the LDS what you expect when you drop off your ancient tanks. If you have a good alloy tank, keep a printout of the Good, the Bad and the Ugly in your glove box so you can enlighten them if needed. It's just not that hard and it's the nice thing to do. You're going to catch a lot more flies with honey than with vinegar. In fact, I simply don't like dealing with mean people. I actively found ways for them to choose another shop when I was a mechanic. Life's just way too short for me to want to deal with mean people. I am not unique in that respect. So, if dive shops are consistently pissing you off, it might not be on accident. I am reminded of that scene from Ghost Town, where the fellow dentist asks the protagonist:
Dr Prashar:
Dr. Pincus, at some point in your life, you're gonna have to stop and ask yourself the ultimate question. This business of... being such a ####### prick, what is it really getting me? Huh?
I get that we live in the "let no good deed go unpunished" society where everyone should be treated like an idiot because they don't agree with you or don't have your mindset. Shenanigans. Communicate clearly what you expect and what you see as a failure right up front. Be nice about it and watch as most people go out of their way to accommodate you. Most shops are ready and willing to do things your way, within reason. Be sure to let them know your needs and desires or be prepared to be disappointed.
