One tactic used by University of Texas students was known as a stand-in. The stand-ins consisted of patrons standing in line at theaters that drew the color line. When participants reached the front of the line, they approached the ticket booth with money and asked whether the theater had reconsidered its Jim Crow policies that required African Americans to sit in a segregated section. After being informed that the theater had not changed its policy, they moved to the back of the line and waited for their next turn to ask if the policy had changed. The stand-ins were effective in limiting the number of tickets that could be sold until the police broke up the demonstrations or escorted white patrons who approved of segregation inside to purchase tickets in the lobby.
