Thats great that you corrected the staff!
I agree, its sad that stores cant take care of their animals properly. I have done that a few times(correcting staff for people) at pet stores. I went in to a PJ's Pet Center once and i was talking to the stores reptile "HEAD EXPERT" asking about a tokay and omg the guy didnt even know what it was, i was teaching him for 10 mins. He didnt even now what the word gravid meant. He said that tokays are friendly and dont bite. Im only 13 too. I thought this was rediculous. I feel sorry for all the animals being improperly kept by pet stores these days and wish i could buy them all(no money
