I don't like the idea of having to clean the glue off my phone because the club is more concerned about people making fools out of themselves in public more than being concerned about my private property, it is sending the wrong message.
When I go to theaters they usually just tell me to turn off my phone or don't take pictures. It has the same weight because people who wouldn't listen would just take the sticker off easily.
If you would have paid attention to my comment you would know that my issue is not social signalling, my issue is getting glue on my phone for a childish reason.
