It's funny how much people don't know about what they are taking care of. I saw an older lady looking for "glow in the dark plants" I told her that there are none there. I told her the benefits of live plants and how glow in the dark plants won't be good for fish because they like to sleep too.
After a while she came back to me about what her sharks would eat and I promptly told her, I even pointed out where the frozen brine shrimp were that she was looking for. Then she started to ask me about lighting and I told her all I knew about that too(I just read a 5 page article about lighting too).
Funny how I knew enough to warrant people wanting to know what I know though. I was hoping to get into a pet shop for a job and this just shows I can if I wanted to.
