Having had my lunches stolen at work in the past (I can't say I blame the person because hey... I make yummy lunches)..... these bags are so perfect. I must get me some of these stat!! Seriously though... what kind of person has the nerve to just take someone else's lunch? The maintenance man at a building I once worked in, used to go through people's lunch bags and take whatever appealed to him. This one lady got so angry that she started keeping her lunch in a bag with a lock on it. Ha! The guy that was rifling through people's food was a pretty nasty dude so after we all found out who was doing it.. ugh... don't want to go there again... I think I might be sick just thinking about it.
