An Oregon couple's tip at a local steakhouse landed them behind bars this week. 

Instead of adding 20% to their bill as their waitress' gratuity 40-year-old Ryan Benson and 37-year-old Erica Manley slipped their server an envelope filled with crystal methamphetamine.

The waitress graciously accepted the "tip," walked away and phoned the police.

Police obtained a warrant to search the couple's nearby Holiday Inn room and discovered a small lab.

Needless to say they won't be visiting any more restaurants any time soon!
