I dont care how busy you are, if you have time to put your snake up for sale then you should have time to provide info on that snake for potential buyers.
Consideration, manners, respect, being understanding and patient work both ways.

Usually when you have your own business you plan one day to clean snakes (and some will have to be cleaned again as they go) one to feed, one to clean rodents, one to feed rodents, and one when you will take pictures place adds and update your website and I am not even covering shipping data keeping etc and of course for some this is on the top of whatever else you might HAVE to do such as work, family etc.

Expecting people to drop everything they are doing for YOU is very inconsiderate in my opinion if you cannot wait 24-48 hours for the breeder to make time to take a picture and email it too you I guess you can take your money somewhere else if that is the case however claiming it is bad customer service or as you said a "scumbag" is just plain wrong.

I wonder have you ever run a small business on the top of having a regular job and juggling with your family obligations?
