IMO working at these big box stores isn't so bad from a moral point of view; i've been considering it as a weekend gig for the extra income. SOMEONE has to work there.
it's the whole "being part of a corporation that has proven their sales are more important than their animals" idea that most people refuse to support these places in any way.
personally i like the idea of being an "inside man" and teaching new or soon-to-be reptile owners real proper care, better product alternatives and, if i can't help, where to find truly knowledgeable people to help them (bp.net woop!) by steering them away from the store lol. of course i would do this on the DL but if i get caught it wouldn't hurt me to lose the job financially or otherwise. this part may not apply to you. it's always refreshing to see us like-minded and educated people working at these stores. it's a little victory for the animals.
all in all it sucks to understand these stores' role as a corporation, but sometimes they have what i need; i just bought a hide for my corn snake at petsmart last week.
it's up to you. no one is going to come after you with pitchforks if you decide to work there lol. 😊 plus, who doesn't like getting an employee discount???
