A few of my own random thoughts-
We've all missed out on animals that were sold to someone else. Until the buyer says "I'll take it" (and the seller acknowledges), there is no deal, and generally that, in and of itself, does not justify a bad guy thread. If the seller is ignoring the buyer's request for info (extremely common among herp dealers, unfortunately), then chalk it up to poor service and move on. I've missed the boat myself more than once, trying to make a decision while somebody else is sending in their money. Life goes on. There are usually more opportunities to buy herps later.
Regarding:
Some else called next and just said ill take them and paypaled me right away like its supposed to work...
I personally disagree with this statement, which suggests that buyers should be expected not to ask questions. I ask a lot of questions when I am buying herps, just as I might when making any other purchase. However I sometimes detect an attitude of impatience from sellers that suggests they would rather I forgo the questions, and just send the money. This can create a negative atmosphere that, even if a transaction is completed, may lead to later dissatisfaction with the purchase. Nobody has such great animals that I'm not going to ask questions.
Regarding the insulting rant:
If one is going to be in business, then one needs to develop a thick skin. There are going to be upset customers, rightfully and not. No matter how much they may tick you off, losing your cool and insulting them is not the professional choice. For some reason, this type of dialogue between buyers and sellers appears to be fairly common in the herp business, and quite rare almost everyplace else. In most non-herp businesses, a rant like this would have gotten the employee fired, or at least severely reprimanded. Self-employed business owners should hold themselves to a higher standard, not a lesser one. In any event, the OP's mild snarkiness didn't remotely warrant this type of response.
