Is that the can that sat in the warehouse and the rats & mice spewed urine & feces on it? Yeah, right, tell me you wash the can before you drink it? Don't forget to load the car with all those dripping cans so you could get your nickel back. Don't care about the deposit? Add that to your cost. Those pallets of Pepsi that sit out front of Stop & Shop? Ever watch the dogs pass and pee on your Coke? Ah, tangy!! Sodastream... soda when you want. Make it fresh with filtered water. Has no trace of urine or feces.
The universe of consumers that would have the slightest concern over the items you mention is smaller than your IQ. Get real. Everything you say could be true and no one is going to care and more importantly affect the price of SODA one iota. You are grasping at straws.
