Though there have been plenty of cell phone rants about diners whipping out their cell phones during meals, and debates on whether or not that behavior is OK, there's a new app that encourages you to use your cell at the table . . . if only to get your waiter's attention.Called TextMyFood, this app allows you to communicate with your server via text message. In restaurants that have implemented the service, you can text your server when you need another round of drinks, more ketchup, the check, have a complaint about your food, whatever, really, instead of trying to flag them down with a wave of your hand. Not only does this seem rather impersonal but kind of annoying for the server. I don't like when my phone blows up with push notifications, text messages, and email alerts, so I can imagine that a packed dining room full of texters would equal stress for the waitstaff. What do you think?
