My husband and I were in our seventies, and every time we went into a casino, we had to show our ID.
If we came out of our hotel room and walked into the casino; we had to show our room key. I thought this was odd, since there was no way someone under 21 was going to look as old as we did. What was hilarious was that we were visiting our daughter, who lived in Las Vegas, NV. She had moved there several years ago, and taken a promotion with the company she worked for. Her husband was working as an electrician in a casino, and our granddaughter was working at the local dog shelter. Although our granddaughter had recently turned 21, she said she had to show her ID when she and our daughter went to the casinos. She looked like she was a little over 12, so I understood that. I went with her one afternoon, when my daughter needed some things to make dinner. While out, my granddaughter stopped at the marijuana dispensary. She said she wanted to pick up a few things and asked me to go in with her. I had never been in a marijuana dispensary, so I followed. We had to show our ID in the casino, but no one asked for our ID when we walked into the marijuana dispensary. My granddaughter said it was because she worked here for almost a year, and everyone knew her. That could have been the reason, but I had a feeling that if the Las Vegas, NV police saw them not looking at ID< this marijuana dispensary would be shut down for a while.
