Las Vegas: El Cortez hotel-casino tests out plexiglass barriers on table games, slot machines Kyla Galer, Fox5 News · May 7, 2020 at 7:35 pm El Cortez Hotel and Casino in downtown Las Vegas is testing out plexiglass barriers or “sneeze guards” on blackjack tables and in between slot machines. Las Vegas-based company Screaming Images designed it. Each player is separated from each other and the dealer by plexiglass. There’s an opening for each player’s hands where chips can pass through. Some people are worried the reflection could lead to cheating. El Cortez General Manager Adam Wiesberg said that shouldn’t be a problem considering how closely each player is monitored by security cameras and pit bosses.
