There are some people who place ads who are very bad mannered when replying to one who has answered thier advert.
The question is why bother to place an Ad at all if the person who answers has to suffer verbal abuse if they don't meet with thier idea of who should or should not apply.
May be hiding behind an email reply they feel safe and undetectable, have I got news for you types, it is unlawful to attack any one verbally, an email can be tracked back to it's originator.
Can they not just say: "Sorry no thanks" or "My book is now full".
Does it cost so much to be polite??
