I think they want you gone as quietly and quickly as possible as you want to leave them,
I think it's mutual at this point.... while I know some would scream and demand everything... I want to be reasonable and I find that Karma is a strange banker, but she rewards you when you do the right thing.
If I were on the other side of this, losing a profitable customer due to employee/contractor misbheavior (and I've been there) I'd want to minimize my loss, cover my hard costs, and part nicely.
I don't expect the shop to eat everything. I want to give them an opportunity to tell me what they think is fair. That is reasonable. If I disagree we can go from there.
At the end of the day, my safety is far more important than $1000 to $2000 which is the maximum damage if they refunded nothing. Even if they got $2k out of me it will cost them FAR FAR more in terms of losing me as a customer. Customer acquisition is one of the single biggest expenses for a small business. customers are incredibly expensive to bring in. Profitable customers who have money to spend and the desire to play are even harder to find. I, by myself, won't impact their bottom line. But if they treated me this way there will be others will nearly identical experiences. These sorts of things don't happen in isolation when there is support from the top.
This is the type of thing that you just can't outrun. You can't ditch customer after customer and make money. Customer service is really, emphatically caring about your customers and going after anyone who doesn't.
I tallied up my purchases at this shop for the year so far.... $6130.43. Now, I'll admit I don't own a dive shop. But I'm also willing to bet you don't find many customers who will spend an average of $1500/mo with you. Do you really want to screw that up? haha..... Bet you I won't have much trouble finding another shop that wants that business and respects me as a customer. On a standard 2 keystone (200%) markup they probably had a gross margin of around $4000 this year from me. In my business I bend over backwards not to piss off those kinds of customers... and any employee who doesn't drink *that* kool-aid is out of here like a bad fart in a fast covertible!
Btw, those purchases do not include a BCD, Reg, Fins, Mask, Wetsuits (3mm and 5mm), weights, dive gear bag, etc. I opted for a used BCD and reg. I had them serviced which is included in those numbers. I bought my fins and mask where I did my OW training which is not included in those numbers. I bought my wetsuits, dive gear bag and some minor accessories from LeisurePro and have to say they get customer service and were pretty nice to work with. I bought the weights on ebay for $2/lb. They look identical to the dive shop weights at $4/lb. I drank the kool-aid for a while, and frankly it was sort of expensive kool-aid and didn't seem to get me anywhere at the end of the day.
Almost forgot.... the numbers above don't include some cash purchases ($200?) and don't include my Camera, Strobe, Pelican Case, or Tray. I bought the tray direct from someone on here in the PNW who makes awesome camera gear. I bought the Canon G9 and Canon Case from someone on ebay who used them in a pool. I bought the pelican case on Ebay as well. Then there was the strobe from Ebay/Estate sale... $70 for a nice Sea & Sea strobe.... YS120. And a fleet of rechargeable batteries (Eneloops) and a quick charger fo rthem. That's easily another $1000 into this hobby. I think the LDS was made I didn't buy a Sealife... which is cute, but I actually can use a camera so I'd have wound Sealife's mousetrap too tight by the time I got it wet.
On the other hand, I'm spending enough to actually go diving where the water is warm and clear. Hmm.... maybe I should be spending more money with IflySWA.com where dive bags fly free (when disguised as regular luggage).
