I believe you are 100% correct DiiQue. When I was asking questions of a Petco employee yesterday all she said was she knew about dogs nothing about fish
It's sad the women employee in Petco told a lady interested in buying a betta that if a betta is being kept in a bowl you didn't need a filter or heater and to just doing water changes every couple of days. My Mouth Dropped to the floor. I quickly had to intervene and advise her on a tank, conditioner and upkeep needed for betta's. I know I am no expert but I knew more than her.
