Final solution - Cell phone jammers

I hate that the jammer is illegal. My second job is at a sandwich shop where there is a lot of interaction with the customers; beginning with the order taking. In order to properly process the order from beginning to end, we have to ask a lot of questions. It is extremely annoying when the customer is standing there talking on the phone & they won’t hang up, or worse, they hold up one finger in the universal “just a minute” sign. I guaranty that is a sure fire way to p*&^s off the person who is making your food and taking your money. LOL For a minute I thought I had the perfect solution. OH WELL!
