Well no but i mean you'd get the idea of it.... I can see a snake and gauge its weight pretty accurately. Idk, i just feel it was a misunderstanding. Bob doesn't seem like a bad guy imo.
If I were you i'd give him a second chance to handle stuff right, if he still has the snake available. It really does seem like an honest mistake/misunderstanding. Now that he's moved he's not gunna be as tied up and short on time so give him a chance to get you some updated pics and prove that he can provide as good of customer service as he says he can. Send him the dough, and get the snake you originally wanted!
