Something that gets under my skin equally as much is customers who refuse to believe you about some things. I mean, I understand that sometimes people offer bad advice or just plain wrong advice, but one would assume that when a lfs employee is offering advice which is resulting in not selling a fish, they had some idea of what they are doing. Mostly I'm just ranting about a customer who bought 6 sunburst platys and a snail today to put in their 10G tank which had been set up for 4 days....sigh...I tried to explain cycling, and how adding that many fish so soon would just be a horrible mess, but "my 5 year old son wants these fish so badly", unfortunately for me my stupid manager was working so the best I could do was take away the 14-day and pray for those poor fish. But yeah, I just see way too many people who will go out of their way to get information from store employees but never think to get another source, and then complain that the employee was wrong about something. The worst is with the turtles though...poor little turtles 
Plus a lot of knowledge is just so dependent on time and experience that it would be hard to expect newer employees to just instantly know everything about every fish/ animal in the store. Try to keep in mind that the employee's in the bigger pet stores (petsmart, petco, etc) also have to know about the small animals and the reptiles. So we have a general knowledge of the a whole bunch of very strange animals, and not specific knowledge of one exact fish.
