The little plastic boxes that they give you at restaurants for leftovers should come with a 4' long thread attached, with a piece of velcro on the end. The thread is attached to your finger, preventing you from leaving the box at the restaurant or in your car.-- DIYMatt, Apr 13 2015 What? Why don't you hang it around your neck?-- xandram, Apr 13 2015 I think this idea fills an unneeded meet.-- MaxwellBuchanan, Apr 13 2015 Good one xandie. Not so sure about the original idea though.-- blissmiss, Apr 13 2015 The "Poor Hungry Cab Drivers and Bar Owners Union" has yet to make a statement on this. ( On the one hand it is food, but on the other it is leftovers. )-- popbottle, Apr 14 2015 random, halfbakery
