@PlasticGalaxy , I'd love to support your shop too, but the commute is prohibitive.
Besides various medical and dental offices, we have a Mexican restaurant (livebearers and cichlids!), a Thai restaurant with an awful aquarium (I'm a bit of a specialist in Thai fish and plants), a casino restaurant on the Indian Reservation that cries out for a native fish tank...so many fun challenges. The only trouble is that I find it very distressing when something goes wrong in a clients tank. Problems that I would face with a shrug and "do the best I can" attitude in my own tanks, become a major crisis when I'm getting paid to do it for someone else. Pesky work ethic.
So, I'd have to learn to be a bit more relaxed and have fun with it. I like making people happy, and fish definitely do!
