ok, I'm gonna sound like a bitch here.
Grow up, take responsibility. You've apparently worked there for a long time, which meant you knew they had no water fountain. Therefore, you could have had the common sense to have brought a beverage with you in the first place.
There are rules to be followed.
You may think you followed them in talking to your manager before getting the pop. Guess what? This is the real world. Your manager may be thinking in "Me vs Him"/"Cover my own butt" mode. It's not right, but it is what you will encounter in the workforce.
Go move on....find another job....because with each day that passes, it's obvious that you are likely not returning to work there. Maybe they are trying to force you to quit. Who knows? But at this point, if you are worried about money....best to get off your butt and start job hunting.
PS: Please do yourself a favor....go see a lawyer with all your questions. We've done our best here, and we are not lawyers.
