From the Bexar county DA office: (I know you're in Bee county, but the law still applies)
"Under penal code section 31.03 Theft, a person commits an offense if he unlawfully appropriates property or secures performance of a service from the owner by deception. The key under the law is that the owner must give the merchandise at the time the check writer renders the check. Furthermore, inducing a provider of services to provide services by giving the provider a check which the issuer knows will be dishonored by the bank qualifies as deception. Again, the key under the law is that the owner must provide the service at the time the check writer renders the check."
Good luck to you, hon.
