Let's try and make the extra effort so that everyone can go out and enjoy themselves and also let those who are already having a good time be allowed to continue.
For a while there, some people who had allergies or did not like noise, thought that they could impose their wishes on others. That is not the case. If you like a peaceful place, that is fine, lots of us like peaceful places too and are quite happy to have a serene evening. However, sometimes some of us might laugh or start a song. But overall, quiet places, stay quiet. It is the same with food preferences. If you like vegan, then order some vegetables but do not make remarks about those that are eating meat. Ditto alcohol or nuts.
