Is it prostitution to take money from someone who is expecting sex, but then not supply it?

A person who doesn't supply sex and takes money is not a prostitute, this is called an escort. An escort is someone paid to go on a date as a companion. A prostitute is someone who sells their body, exchanges sex for money.

Is it sociably respectable?

• Could be because the person is not exactly selling their body.
  
• Or could be less socially respectable because their taking money without supplying the sex and portraying themselves as a prostitute.
  

Is this Being Bad?

My opinion... for someone to pay an prostitute money without receiving sex is allowing that person to take them for a fool. It's not theft if the person hasn't said they would be supplying sex at the end of the night exchange for the money.
