If I didn't have kids I wouldn't even bother leaving mine on when I went out with friends.When my friends and I go to resto we play Cell Phone Jenga. At the start of the meal we put our cellphone right in the middle of the table, one stacked upon the other neatly and leave it there during the entire supper. No calls being made. No calls received. No texting. Nothing. Once everyone gets there. We stack them. Then we enjoy our evening.
The first person to touch their cellphone before the end of supper pays everyone's dinner.
This has happened once and since then, never has been much of an issue.
