All too often people "white knight" manufacturers because they have a personal connection or they are just overly happy with the end product. Which there is nothing wrong with. But these people seem to skip over why the person complaining is, well, complaining.
OP, nor anyone else, ever said the people at Hefty were bad people, crooks, or anything of the like. But people almost seemed to be offended that someone had a complaint. That's just not just this board, its all of them.
How about this. You go to restaurant where you pay then receive your food. But there is a delay and they tell you it'll be 5 minutes. But suddenly its 10. At 15 minutes you ask what's going on but the person who cashed you out either doesn't talk to you or just says 5 more minutes. Its now 25 minutes. Guy walking out after eating tells you the owner is back there with his family busting his ass and they are all stand up people and the food is rated 5 out of 5 stars. But you hear nothing from any employee. Its now 30 minutes. See where I'm going?
It doesn't matter what the product is, how much it is, how great it will be, or how great the person making it is. If you fail to deliver on time and can't communicate with someone who spent their hard earned money with you, then that's not "good hands." YMMV.
