I just went into CVS pharmacy to buy a drink (Starbucks Coffee) drank it and went on my hike. An hour an a half into my hike, had horrible stomach pains to the point where I soiled myself because there were no restrooms around. Got home and still experiencing pains. Decided to check the sell by date on the coffee as that's the only thing I've had and it's half a month past due. It's embarrassing and I went through hell. What can I do besides just a refund? I'm absolutely furious because not only did my new girlfriend witness all of this but it's scarring to myself now.
