They said they caught him and escorted him out. There was a man that was walking by our table and sprayed something into the air behind us. He called the security people and they watched the video of our table. The pit boss came over and we made a complaint that something was wrong. Two people at the next table over began coughing. We all had a ticklish cough with a burning throat. As we were playing everyone (6 people) started to cough. The ante was $15 per hand (high in my opinion for a Monday morning). We were playing a table game called 'Casino War'. I travelled from Missouri to visit my nephew in Richmond and as a fun day out we went to the MGM casino. It was one of the first outings we had taken since January 2020 due to the pandemic. My family went to the MGM in Maryland for a day trip.
