Missing word: "The Bartender is not permitted to carry their shotgun outside the bar. However, they may obtain permission from the Head of Security to shorten the barrel for easier transportation. Shortening the barrel without authorization is grounds for confiscation of the Bartender's shotgun;"
"The Mime is permitted to use written words to communicate, but only during emergency situations or during official testimonials;"
There's plenty of other situations where it's impossible or problematic to mime what you need without writing, such as requesting something highly specific from the bar or R&D. Also, the only way to get people's attention remotely without miming is via PDA. I'm not sure how a better version would be phrased to still encourage minimizing that, though.
